Trait Implementations

impl<'tcx> Clone for ProjectionCacheKey<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ProjectionCacheKey<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Hash for ProjectionCacheKey<'tcx>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx> PartialEq for ProjectionCacheKey<'tcx>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'cx, 'tcx> ProjectionCacheKeyExt<'cx, 'tcx> for ProjectionCacheKey<'tcx>

fn from_poly_projection_obligation( selcx: &mut SelectionContext<'cx, 'tcx>, obligation: &PolyProjectionObligation<'tcx>, ) -> Option<Self>

impl<'tcx> Copy for ProjectionCacheKey<'tcx>

impl<'tcx> Eq for ProjectionCacheKey<'tcx>

impl<'tcx> StructuralPartialEq for ProjectionCacheKey<'tcx>

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.
