Struct rustc_middle::ty::adjustment::OverloadedDeref

pub struct OverloadedDeref<'tcx> {
    pub region: Region<'tcx>,
    pub mutbl: Mutability,
    pub span: Span,
}

An overloaded autoderef step, representing a Deref(Mut)::deref(_mut) call, with the signature &'a T -> &'a U or &'a mut T -> &'a mut U. The target type is U in both cases, with the region and mutability being those shared by both the receiver and the returned reference.

Fields

region: Region<'tcx>

mutbl: Mutability

span: Span

The Span associated with the field access or method call that triggered this overloaded deref.

Implementations

impl<'tcx> OverloadedDeref<'tcx>

pub fn method_call(&self, tcx: TyCtxt<'tcx>, source: Ty<'tcx>) -> Ty<'tcx>

Get the zst function item type for this method call.

Trait Implementations

impl<'tcx> Clone for OverloadedDeref<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for OverloadedDeref<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for OverloadedDeref<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for OverloadedDeref<'tcx>

fn encode(&self, __encoder: &mut __E)

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

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

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

type Lifted = OverloadedDeref<'__lifted>

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

impl<'tcx> PartialEq<OverloadedDeref<'tcx>> for OverloadedDeref<'tcx>

fn eq(&self, other: &OverloadedDeref<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for OverloadedDeref<'tcx>

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

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Selfwhere F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for OverloadedDeref<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V ) -> ControlFlow<__V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

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.
