Trait Implementations

impl<'tcx> Clone for DropckOutlives<'tcx>

fn clone(&self) -> DropckOutlives<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for DropckOutlives<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, '__ctx> HashStable<StableHashingContext> for DropckOutlives<'tcx>

fn hash_stable(
    &self,
    __hcx: &mut StableHashingContext<'__ctx>,
    __hasher: &mut StableHasher
)

impl<'tcx, '__lifted> Lift<'__lifted> for DropckOutlives<'tcx>

type Lifted = DropckOutlives<'__lifted>

fn lift_to_tcx(
    self,
    __tcx: TyCtxt<'__lifted>
) -> Option<DropckOutlives<'__lifted>>

impl<'tcx> QueryTypeOp<'tcx> for DropckOutlives<'tcx>

type QueryResponse = DropckOutlivesResult<'tcx>

fn try_fast_path(
    tcx: TyCtxt<'tcx>,
    key: &ParamEnvAnd<'tcx, Self>
) -> Option<Self::QueryResponse>

Give query the option for a simple fast path that never actually hits the tcx cache lookup etc. Return Some(r) with a final result or None to do the full path.

fn perform_query(
    tcx: TyCtxt<'tcx>,
    canonicalized: Canonicalized<'tcx, ParamEnvAnd<'tcx, Self>>
) -> Fallible<CanonicalizedQueryResponse<'tcx, Self::QueryResponse>>

Performs the actual query with the canonicalized key – the real work happens here. This method is not given an infcx because it shouldn’t need one – and if it had access to one, it might do things like invoke sub_regions, which would be bad, because it would create subregion relationships that are not captured in the return value.

fn fully_perform_into(
    query_key: ParamEnvAnd<'tcx, Self>,
    infcx: &InferCtxt<'_, 'tcx>,
    output_query_region_constraints: &mut QueryRegionConstraints<'tcx>
) -> Fallible<(Self::QueryResponse, Option<Canonical<'tcx, ParamEnvAnd<'tcx, Self>>>, PredicateObligations<'tcx>, Certainty)>

impl<'tcx> TypeFoldable<'tcx> for DropckOutlives<'tcx>

fn try_super_fold_with<__F: FallibleTypeFolder<'tcx>>(
    self,
    __folder: &mut __F
) -> Result<Self, __F::Error>

fn super_visit_with<__F: TypeVisitor<'tcx>>(
    &self,
    __folder: &mut __F
) -> ControlFlow<__F::BreakTy>

fn super_fold_with<F>(self, folder: &mut F) -> Self where
    F: TypeFolder<'tcx, Error = !>, 

Consumers may find this more convenient to use with infallible folders than try_super_fold_with, to which the provided default definition delegates. Implementors should not override this provided default definition, to ensure that the two methods are coherent (provide a definition of try_super_fold_with instead).

fn fold_with<F>(self, folder: &mut F) -> Self where
    F: TypeFolder<'tcx, Error = !>, 

Consumers may find this more convenient to use with infallible folders than try_fold_with, to which the provided default definition delegates. Implementors should not override this provided default definition, to ensure that the two methods are coherent (provide a definition of try_fold_with instead).

fn try_fold_with<F>(
    self,
    folder: &mut F
) -> Result<Self, <F as TypeFolder<'tcx>>::Error> where
    F: FallibleTypeFolder<'tcx>, 

fn visit_with<V>(
    &self,
    visitor: &mut V
) -> ControlFlow<<V as TypeVisitor<'tcx>>::BreakTy, ()> where
    V: TypeVisitor<'tcx>, 

fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free.

fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

Returns true if this self has any regions that escape binder (and hence are not bound by it).

fn has_escaping_bound_vars(&self) -> bool

fn has_type_flags(&self, flags: TypeFlags) -> bool

fn has_projections(&self) -> bool

fn has_opaque_types(&self) -> bool

fn references_error(&self) -> bool

fn has_param_types_or_consts(&self) -> bool

fn has_infer_regions(&self) -> bool

fn has_infer_types(&self) -> bool

fn has_infer_types_or_consts(&self) -> bool

fn needs_infer(&self) -> bool

fn has_placeholders(&self) -> bool

fn needs_subst(&self) -> bool

fn has_free_regions(&self) -> bool

“Free” regions in this context means that it has any region that is not (a) erased or (b) late-bound.

fn has_erased_regions(&self) -> bool

fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.

fn is_global(&self) -> bool

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching.

fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions

fn still_further_specializable(&self) -> bool

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization.

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.
