Trait Implementations

impl<'tcx> PrettyPrinter<'tcx> for AbsolutePathPrinter<'tcx>

fn should_print_region(&self, _region: Region<'_>) -> bool

Returns true if the region should be printed in optional positions, e.g., &'a T or dyn Tr + 'b. This is typically the case for all non-'_ regions.

fn comma_sep<T>(
    self,
    elems: impl Iterator<Item = T>
) -> Result<Self, Self::Error>where
    T: Print<'tcx, Self, Output = Self, Error = Self::Error>,

Prints comma-separated elements.

fn generic_delimiters(
    self,
    f: impl FnOnce(Self) -> Result<Self, Self::Error>
) -> Result<Self, Self::Error>

Prints <...> around what f prints.

fn should_print_verbose(&self) -> bool

fn print_value_path(
    self,
    def_id: DefId,
    substs: &'tcx [GenericArg<'tcx>]
) -> Result<Self::Path, Self::Error>

Like print_def_path but for value paths.

fn in_binder<T>(self, value: &Binder<'tcx, T>) -> Result<Self, Self::Error>where
    T: Print<'tcx, Self, Output = Self, Error = Self::Error> + TypeFoldable<'tcx>,

fn wrap_binder<T, F>(
    self,
    value: &Binder<'tcx, T>,
    f: F
) -> Result<Self, Self::Error>where
    F: FnOnce(&T, Self) -> Result<Self, Error>,
    T: Print<'tcx, Self, Output = Self, Error = Self::Error> + TypeFoldable<'tcx>,

fn typed_value(
    self,
    f: impl FnOnce(Self) -> Result<Self, Self::Error>,
    t: impl FnOnce(Self) -> Result<Self, Self::Error>,
    conversion: &str
) -> Result<Self::Const, Self::Error>

Prints {f: t} or {f as t} depending on the cast argument

fn try_print_visible_def_path(
    self,
    def_id: DefId
) -> Result<(Self, bool), Self::Error>

If possible, this returns a global path resolving to def_id that is visible from at least one local module, and returns true. If the crate defining def_id is declared with an extern crate, the path is guaranteed to use the extern crate.

fn try_print_trimmed_def_path(
    self,
    def_id: DefId
) -> Result<(Self::Path, bool), Self::Error>

Try to see if this path can be trimmed to a unique symbol name.

fn try_print_visible_def_path_recur(
    self,
    def_id: DefId,
    callers: &mut Vec<DefId, Global>
) -> Result<(Self, bool), Self::Error>

Does the work of try_print_visible_def_path, building the full definition path recursively before attempting to post-process it into the valid and visible version that accounts for re-exports.

fn pretty_path_qualified(
    self,
    self_ty: Ty<'tcx>,
    trait_ref: Option<TraitRef<'tcx>>
) -> Result<Self::Path, Self::Error>

fn pretty_path_append_impl(
    self,
    print_prefix: impl FnOnce(Self) -> Result<Self::Path, Self::Error>,
    self_ty: Ty<'tcx>,
    trait_ref: Option<TraitRef<'tcx>>
) -> Result<Self::Path, Self::Error>

fn pretty_print_type(self, ty: Ty<'tcx>) -> Result<Self::Type, Self::Error>

fn pretty_print_opaque_impl_type(
    self,
    def_id: DefId,
    substs: &'tcx List<GenericArg<'tcx>>
) -> Result<Self::Type, Self::Error>

fn insert_trait_and_projection(
    &mut self,
    trait_ref: Binder<'tcx, TraitRef<'tcx>>,
    proj_ty: Option<(DefId, Binder<'tcx, Term<'tcx>>)>,
    traits: &mut IndexMap<Binder<'tcx, TraitRef<'tcx>>, IndexMap<DefId, Binder<'tcx, Term<'tcx>>, BuildHasherDefault<FxHasher>>, BuildHasherDefault<FxHasher>>,
    fn_traits: &mut IndexMap<Binder<'tcx, TraitRef<'tcx>>, OpaqueFnEntry<'tcx>, BuildHasherDefault<FxHasher>>
)

Insert the trait ref and optionally a projection type associated with it into either the traits map or fn_traits map, depending on if the trait is in the Fn* family of traits.

fn pretty_print_bound_var(
    &mut self,
    debruijn: DebruijnIndex,
    var: BoundVar
) -> Result<(), Self::Error>

fn ty_infer_name(&self, TyVid) -> Option<Symbol>

fn const_infer_name(&self, ConstVid<'tcx>) -> Option<Symbol>

fn pretty_print_dyn_existential(
    self,
    predicates: &'tcx List<Binder<'tcx, ExistentialPredicate<'tcx>>>
) -> Result<Self::DynExistential, Self::Error>

fn pretty_fn_sig(
    self,
    inputs: &[Ty<'tcx>],
    c_variadic: bool,
    output: Ty<'tcx>
) -> Result<Self, Self::Error>

fn pretty_print_const(
    self,
    ct: Const<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>

fn pretty_print_const_scalar(
    self,
    scalar: Scalar<AllocId>,
    ty: Ty<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>

fn pretty_print_const_scalar_ptr(
    self,
    ptr: Pointer<AllocId>,
    ty: Ty<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>

fn pretty_print_const_scalar_int(
    self,
    int: ScalarInt,
    ty: Ty<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>

fn pretty_print_const_pointer<Prov>(
    self,
    Pointer<Prov>,
    ty: Ty<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>where
    Prov: Provenance,

This is overridden for MIR printing because we only want to hide alloc ids from users, not from MIR where it is actually useful.

fn pretty_print_byte_str(
    self,
    byte_str: &'tcx [u8]
) -> Result<Self::Const, Self::Error>

fn pretty_print_const_valtree(
    self,
    valtree: ValTree<'tcx>,
    ty: Ty<'tcx>,
    print_ty: bool
) -> Result<Self::Const, Self::Error>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
