[−][src]Struct rustc_middle::ty::query::Queries
Fields
on_disk_cache: Option<OnDiskCache<'tcx>>This provides access to the incremental compilation on-disk cache for query results.
Do not access this directly. It is only meant to be used by
DepGraph::try_mark_green() and the query infrastructure.
This is None if we are not incremental compilation mode
providers: IndexVec<CrateNum, Providers>fallback_extern_providers: Box<Providers>trigger_delay_span_bug: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ()>>[query description - consider adding a doc-comment!] trigger a delay span bug
hir_crate: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, &'tcx Crate<'tcx>>>Represents crate as a whole (as distinct from the top-level crate module).
If you call hir_crate (e.g., indirectly by calling tcx.hir().krate()),
we will have to assume that any change means that you need to be recompiled.
This is because the hir_crate query gives you access to all other items.
To avoid this fate, do not call tcx.hir().krate(); instead,
prefer wrappers like tcx.visit_all_items_in_krate().
index_hir: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, &'tcx IndexedHir<'tcx>>>The indexed HIR. This can be conveniently accessed by tcx.hir().
Avoid calling this query directly.
hir_module_items: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, &'tcx ModuleItems>>The items in a module.
This can be conveniently accessed by tcx.hir().visit_item_likes_in_module.
Avoid calling this query directly.
hir_owner: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, Option<&'tcx Owner<'tcx>>>>Gives access to the HIR node for the HIR owner key.
This can be conveniently accessed by methods on tcx.hir().
Avoid calling this query directly.
hir_owner_nodes: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, Option<&'tcx OwnerNodes<'tcx>>>>Gives access to the HIR nodes and bodies inside the HIR owner key.
This can be conveniently accessed by methods on tcx.hir().
Avoid calling this query directly.
opt_const_param_of: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, Option<DefId>>>Computes the DefId of the corresponding const parameter in case the key is a
const argument and returns None otherwise.
let a = foo::<7>(); // ^ Calling `opt_const_param_of` for this argument, fn foo<const N: usize>() // ^ returns this `DefId`. fn bar() { // ^ While calling `opt_const_param_of` for other bodies returns `None`. }
type_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx TyS<'tcx>>>Records the type of every item.
analysis: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, Result<(), ErrorReported>>>[query description - consider adding a doc-comment!] running analysis passes on this crate
generics_of: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, Generics>>Maps from the DefId of an item (trait/struct/enum/fn) to its
associated generics.
predicates_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, GenericPredicates<'tcx>>>Maps from the DefId of an item (trait/struct/enum/fn) to the
predicates (where-clauses) that must be proven true in order
to reference it. This is almost always the "predicates query"
that you want.
predicates_of builds on predicates_defined_on -- in fact,
it is almost always the same as that query, except for the
case of traits. For traits, predicates_of contains
an additional Self: Trait<...> predicate that users don't
actually write. This reflects the fact that to invoke the
trait (e.g., via Default::default) you must supply types
that actually implement the trait. (However, this extra
predicate gets in the way of some checks, which are intended
to operate over only the actual where-clauses written by the
user.)
explicit_item_bounds: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx [(Predicate<'tcx>, Span)]>>Returns the list of bounds that can be used for
SelectionCandidate::ProjectionCandidate(_) and
ProjectionTyCandidate::TraitDef.
Specifically this is the bounds written on the trait's type
definition, or those after the impl keyword
type X: Bound + 'lt // ^^^^^^^^^^^ impl Debug + Display // ^^^^^^^^^^^^^^^
key is the DefId of the associated type or opaque type.
Bounds from the parent (e.g. with nested impl trait) are not included.
item_bounds: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx List<Predicate<'tcx>>>>Elaborated version of the predicates from explicit_item_bounds.
For example:
trait MyTrait { type MyAType: Eq + ?Sized; }
explicit_item_bounds returns [<Self as MyTrait>::MyAType: Eq],
and item_bounds returns
[
<Self as Trait>::MyAType: Eq,
<Self as Trait>::MyAType: PartialEq<<Self as Trait>::MyAType>
]
Bounds from the parent (e.g. with nested impl trait) are not included.
projection_ty_from_predicates: QueryState<DepKind, Query<'tcx>, DefaultCache<(DefId, DefId), Option<ProjectionTy<'tcx>>>>[query description - consider adding a doc-comment!] finding projection type inside predicates of tcx.def_path_str(key.0)
native_libraries: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, Rc<Vec<NativeLib, Global>>>>[query description - consider adding a doc-comment!] looking up the native libraries of a linked crate
lint_levels: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, CrateNum, LintLevelMap>>[query description - consider adding a doc-comment!] computing the lint levels for items in this crate
parent_module_from_def_id: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, LocalDefId>>[query description - consider adding a doc-comment!] parent module of tcx.def_path_str(key.to_def_id())
expn_that_defined: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ExpnId>>Internal helper query. Use tcx.expansion_that_defined instead
is_panic_runtime: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, bool>>[query description - consider adding a doc-comment!] checking if the crate is_panic_runtime
mir_keys: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, CrateNum, HashSet<LocalDefId, BuildHasherDefault<FxHasher>>>>Set of all the DefIds in this crate that have MIR associated with
them. This includes all the body owners, but also things like struct
constructors.
mir_const_qualif: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ConstQualifs>>Maps DefId's that have an associated mir::Body to the result
of the MIR const-checking pass. This is the set of qualifs in
the final value of a const.
mir_const_qualif_const_arg: QueryState<DepKind, Query<'tcx>, DefaultCache<(LocalDefId, DefId), ConstQualifs>>[query description - consider adding a doc-comment!] const checking the const argument tcx.def_path_str(key.0.to_def_id())
mir_built: QueryState<DepKind, Query<'tcx>, DefaultCache<WithOptConstParam<LocalDefId>, &'tcx Steal<Body<'tcx>>>>Fetch the MIR for a given DefId right after it's built - this includes
unreachable code.
mir_const: QueryState<DepKind, Query<'tcx>, DefaultCache<WithOptConstParam<LocalDefId>, &'tcx Steal<Body<'tcx>>>>Fetch the MIR for a given DefId up till the point where it is
ready for const qualification.
See the README for the mir module for details.
mir_abstract_const: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Result<Option<&'tcx [Node<'tcx>]>, ErrorReported>>>Try to build an abstract representation of the given constant.
mir_abstract_const_of_const_arg: QueryState<DepKind, Query<'tcx>, DefaultCache<(LocalDefId, DefId), Result<Option<&'tcx [Node<'tcx>]>, ErrorReported>>>Try to build an abstract representation of the given constant.
try_unify_abstract_consts: QueryState<DepKind, Query<'tcx>, DefaultCache<((WithOptConstParam<DefId>, &'tcx List<GenericArg<'tcx>>), (WithOptConstParam<DefId>, &'tcx List<GenericArg<'tcx>>)), bool>>[query description - consider adding a doc-comment!] trying to unify the generic constants tcx.def_path_str(key.0.0.did) and tcx.def_path_str(key.1.0.did)
mir_drops_elaborated_and_const_checked: QueryState<DepKind, Query<'tcx>, DefaultCache<WithOptConstParam<LocalDefId>, &'tcx Steal<Body<'tcx>>>>[query description - consider adding a doc-comment!] elaborating drops for tcx.def_path_str(key.did.to_def_id())
mir_promoted: QueryState<DepKind, Query<'tcx>, DefaultCache<WithOptConstParam<LocalDefId>, (&'tcx Steal<Body<'tcx>>, &'tcx Steal<IndexVec<Promoted, Body<'tcx>>>)>>[query description - consider adding a doc-comment!] processing if key.const_param_did.is_some() { "the const argument " } else { "" } tcx.def_path_str(key.did.to_def_id())
optimized_mir: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx Body<'tcx>>>MIR after our optimization passes have run. This is MIR that is ready for codegen. This is also the only query that can fetch non-local MIR, at present.
optimized_mir_of_const_arg: QueryState<DepKind, Query<'tcx>, DefaultCache<(LocalDefId, DefId), &'tcx Body<'tcx>>>[query description - consider adding a doc-comment!] optimizing MIR for the const argument tcx.def_path_str(key.0.to_def_id())
coverageinfo: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, CoverageInfo>>Returns coverage summary info for a function, after executing the InstrumentCoverage
MIR pass (assuming the -Zinstrument-coverage option is enabled).
covered_file_name: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, Option<Symbol>>>Returns the name of the file that contains the function body, if instrumented for coverage.
covered_code_regions: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, Vec<&'tcx CodeRegion, Global>>>Returns the CodeRegions for a function that has instrumented coverage, in case the
function was optimized out before codegen, and before being added to the Coverage Map.
promoted_mir: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx IndexVec<Promoted, Body<'tcx>>>>The DefId is the DefId of the containing MIR body. Promoteds do not have their own
DefId. This function returns all promoteds in the specified body. The body references
promoteds by the DefId and the mir::Promoted index. This is necessary, because
after inlining a body may refer to promoteds from other bodies. In that case you still
need to use the DefId of the original body.
promoted_mir_of_const_arg: QueryState<DepKind, Query<'tcx>, DefaultCache<(LocalDefId, DefId), &'tcx IndexVec<Promoted, Body<'tcx>>>>[query description - consider adding a doc-comment!] optimizing promoted MIR for the const argument tcx.def_path_str(key.0.to_def_id())
erase_regions_ty: QueryState<DepKind, Query<'tcx>, DefaultCache<&'tcx TyS<'tcx>, &'tcx TyS<'tcx>>>Erases regions from ty to yield a new type.
Normally you would just use tcx.erase_regions(value),
however, which uses this query as a kind of cache.
wasm_import_module_map: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, CrateNum, HashMap<DefId, String, BuildHasherDefault<FxHasher>>>>[query description - consider adding a doc-comment!] wasm import module map
predicates_defined_on: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, GenericPredicates<'tcx>>>Maps from the DefId of an item (trait/struct/enum/fn) to the
predicates (where-clauses) directly defined on it. This is
equal to the explicit_predicates_of predicates plus the
inferred_outlives_of predicates.
trait_explicit_predicates_and_bounds: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, GenericPredicates<'tcx>>>Returns everything that looks like a predicate written explicitly by the user on a trait item.
Traits are unusual, because predicates on associated types are converted into bounds on that type for backwards compatibility:
trait X where Self::U: Copy { type U; }
becomes
trait X { type U: Copy; }
explicit_predicates_of and explicit_item_bounds will then take
the appropriate subsets of the predicates here.
explicit_predicates_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, GenericPredicates<'tcx>>>Returns the predicates written explicitly by the user.
inferred_outlives_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx [(Predicate<'tcx>, Span)]>>Returns the inferred outlives predicates (e.g., for struct Foo<'a, T> { x: &'a T }, this would return T: 'a).
super_predicates_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, GenericPredicates<'tcx>>>Maps from the DefId of a trait to the list of
super-predicates. This is a subset of the full list of
predicates. We store these in a separate map because we must
evaluate them even during type conversion, often before the
full predicates are available (note that supertraits have
additional acyclicity requirements).
type_param_predicates: QueryState<DepKind, Query<'tcx>, DefaultCache<(DefId, LocalDefId), GenericPredicates<'tcx>>>To avoid cycles within the predicates of a single item we compute
per-type-parameter predicates for resolving T::AssocTy.
trait_def: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, TraitDef>>[query description - consider adding a doc-comment!] computing trait definition for tcx.def_path_str(key)
adt_def: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx AdtDef>>[query description - consider adding a doc-comment!] computing ADT definition for tcx.def_path_str(key)
adt_destructor: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<Destructor>>>[query description - consider adding a doc-comment!] computing Drop impl for tcx.def_path_str(key)
adt_sized_constraint: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, AdtSizedConstraint<'tcx>>>[query description - consider adding a doc-comment!] computing Sized constraints for tcx.def_path_str(key)
adt_dtorck_constraint: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Result<DtorckConstraint<'tcx>, NoSolution>>>[query description - consider adding a doc-comment!] computing drop-check constraints for tcx.def_path_str(key)
is_const_fn_raw: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, bool>>Returns true if this is a const fn, use the is_const_fn to know whether your crate
actually sees it as const fn (e.g., the const-fn-ness might be unstable and you might
not have the feature gate active).
Do not call this function manually. It is only meant to cache the base data for the
is_const_fn function.
is_const_impl_raw: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, bool>>Returns true if this is a const impl. Do not call this function manually.
This query caches the base data for the is_const_impl helper function, which also
takes into account stability attributes (e.g., #[rustc_const_unstable]).
asyncness: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, IsAsync>>[query description - consider adding a doc-comment!] checking if the function is async: tcx.def_path_str(key)
is_promotable_const_fn: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, bool>>Returns true if calls to the function may be promoted.
This is either because the function is e.g., a tuple-struct or tuple-variant
constructor, or because it has the #[rustc_promotable] attribute. The attribute should
be removed in the future in favour of some form of check which figures out whether the
function does not inspect the bits of any of its arguments (so is essentially just a
constructor function).
is_foreign_item: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, bool>>Returns true if this is a foreign item (i.e., linked via extern { ... }).
static_mutability: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<Mutability>>>Returns Some(mutability) if the node pointed to by def_id is a static item.
generator_kind: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<GeneratorKind>>>Returns Some(generator_kind) if the node pointed to by def_id is a generator.
crate_variances: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, CrateNum, CrateVariancesMap<'tcx>>>Gets a map with the variance of every item; use item_variance instead.
variances_of: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx [Variance]>>Maps from the DefId of a type or region parameter to its (inferred) variance.
inferred_outlives_crate: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, CrateNum, CratePredicatesMap<'tcx>>>Maps from thee DefId of a type to its (inferred) outlives.
associated_item_def_ids: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx [DefId]>>Maps from an impl/trait DefId to a list of the DefId`s of its items.
associated_item: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, AssocItem>>Maps from a trait item to the trait item "descriptor".
associated_items: QueryState<DepKind, Query<'tcx>, ArenaCache<'tcx, DefId, AssociatedItems<'tcx>>>Collects the associated items defined on a trait or impl.
impl_trait_ref: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<TraitRef<'tcx>>>>Given an impl_id, return the trait it implements.
Return None if this is an inherent impl.
impl_polarity: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ImplPolarity>>[query description - consider adding a doc-comment!] computing implementation polarity of tcx.def_path_str(impl_id)
issue33140_self_ty: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<&'tcx TyS<'tcx>>>>[query description - consider adding a doc-comment!] computing Self type wrt issue #33140 tcx.def_path_str(key)
inherent_impls: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx [DefId]>>Maps a DefId of a type to a list of its inherent impls.
Contains implementations of methods that are inherent to a type.
Methods in these implementations don't need to be exported.
unsafety_check_result: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, &'tcx UnsafetyCheckResult>>The result of unsafety-checking this LocalDefId.
unsafety_check_result_for_const_arg: QueryState<DepKind, Query<'tcx>, DefaultCache<(LocalDefId, DefId), &'tcx UnsafetyCheckResult>>[query description - consider adding a doc-comment!] unsafety-checking the const argument tcx.def_path_str(key.0.to_def_id())
unsafe_derive_on_repr_packed: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, ()>>HACK: when evaluated, this reports a "unsafe derive on repr(packed)" error.
Unsafety checking is executed for each method separately, but we only want to emit this error once per derive. As there are some impls with multiple methods, we use a query for deduplication.
fn_sig: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Binder<FnSig<'tcx>>>>The signature of functions.
lint_mod: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, ()>>[query description - consider adding a doc-comment!] linting describe_as_module(key, tcx)
check_mod_attrs: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, ()>>Checks the attributes in the module.

check_mod_impl_wf: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, ()>>[query description - consider adding a doc-comment!] checking that impls are well-formed in describe_as_module(key, tcx)

diagnostic_only_typeck: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, &'tcx TypeckResults<'tcx>>>[query description - consider adding a doc-comment!] type-checking tcx.def_path_str(key.to_def_id())
used_trait_imports: QueryState<DepKind, Query<'tcx>, DefaultCache<LocalDefId, &'tcx HashSet<LocalDefId, BuildHasherDefault<FxHasher>>>>[query description - consider adding a doc-comment!] used_trait_imports tcx.def_path_str(key.to_def_id())
has_typeck_results: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, bool>>[query description - consider adding a doc-comment!] checking whether tcx.def_path_str(def_id) has a body

Do not use this directly, use one of the following wrappers: tcx.const_eval_poly,
tcx.const_eval_resolve, tcx.const_eval_instance, or tcx.const_eval_global_id.
destructure_const: QueryState<DepKind, Query<'tcx>, DefaultCache<ParamEnvAnd<'tcx, &'tcx Const<'tcx>>, DestructuredConst<'tcx>>>Destructure a constant ADT or array into its variant index and its field values.

region_scope_tree: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, &'tcx ScopeTree>>Per-body region::ScopeTree. The DefId should be the owner DefId for the body;

all_local_trait_impls: QueryState<DepKind, Query<'tcx>, DefaultCache<CrateNum, &'tcx BTreeMap<DefId, Vec<HirId, Global>>>>Return all impl blocks in the current crate.
To allow caching this between crates, you must pass in LOCAL_CRATE as the crate number.
Passing in any other crate will cause an ICE.

param_env: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ParamEnv<'tcx>>>Gets the ParameterEnvironment for a given item; this environment
will be in "user-facing" mode, meaning that it is suitable for
type-checking etc, and it does not normalize specializable
associated types. This is almost always what you want,
unless you are doing MIR optimizations, in which case you
might want to use reveal_all() method to change modes.
param_env_reveal_all_normalized: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, ParamEnv<'tcx>>>Like param_env, but returns the ParamEnv in Reveal::Allmode. Prefer this overtcx.param_env(def_id).with_reveal_all_normalized(tcx)`,
as this method is more efficient.
is_copy_raw: QueryState<DepKind, Query<'tcx>, DefaultCache<ParamEnvAnd<'tcx, &'tcx TyS<'tcx>>, bool>>Trait selection queries. These are best used by invoking ty.is_copy_modulo_regions(),

to because they are exported from upstream crates. Do not depend on
this directly, as its value changes anytime a monomorphization gets
added or removed in any upstream crate. Instead use the narrower
upstream_monomorphizations_for, upstream_drop_glue_for, or, even
better, Instance::upstream_monomorphization().
upstream_monomorphizations_for: QueryState<DepKind, Query<'tcx>, DefaultCache<DefId, Option<&'tcx HashMap<&'tcx List<GenericArg<'tcx>>, CrateNum, BuildHasherDefault<FxHasher>>>>>Returns the set of upstream monomorphizations available for the
generic function identified by the given def_id. The query makes
sure to make a stable selection if the same monomorphization is
available in multiple upstream crates.
You likely want to call Instance::upstream_monomorphization()
instead of invoking this query directly.
upstream_drop_glue_for: QueryState<DepKind, Query<'tcx>, DefaultCache<&'tcx List<GenericArg<'tcx>>, Option<CrateNum>>>Returns the upstream crate that exports drop-glue for the given
type (substs is expected to be a single-item list containing the
type one wants drop-glue for).
This is a subset of upstream_monomorphizations_for in order to
increase dep-tracking granularity. Otherwise adding or removing any
type with drop-glue in any upstream crate would invalidate all
functions calling drop-glue of an upstream type.
You likely want to call Instance::upstream_monomorphization()
instead of invoking this query directly.
NOTE: This query could easily be extended to also support other
common functions that have are large set of monomorphizations
(like Clone::clone for example).
