Trait Implementations

impl<'tcx, T> Clone for QueryInput<'tcx, T>

where T: Clone,

fn clone(&self) -> QueryInput<'tcx, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx, T> Debug for QueryInput<'tcx, T>

where T: Debug,

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

Formats the value using the given formatter.

impl<'tcx, T> Hash for QueryInput<'tcx, T>

where T: Hash,

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, '__ctx, T> HashStable<StableHashingContext<'__ctx>> for QueryInput<'tcx, T>

where T: HashStable<StableHashingContext<'__ctx>>,

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

impl<'tcx, T> PartialEq for QueryInput<'tcx, T>

where T: PartialEq,

fn eq(&self, other: &QueryInput<'tcx, T>) -> 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, T> TypeFoldable<TyCtxt<'tcx>> for QueryInput<'tcx, T>

where T: TypeFoldable<TyCtxt<'tcx>>,

fn try_fold_with<__F>( self, __folder: &mut __F ) -> Result<QueryInput<'tcx, T>, <__F as FallibleTypeFolder<TyCtxt<'tcx>>>::Error>

where __F: FallibleTypeFolder<TyCtxt<'tcx>>,

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) -> Self

where 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, T> TypeVisitable<TyCtxt<'tcx>> for QueryInput<'tcx, T>

where T: TypeVisitable<TyCtxt<'tcx>>,

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

where __V: TypeVisitor<TyCtxt<'tcx>>,

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

impl<'tcx, T> Copy for QueryInput<'tcx, T>

where T: Copy,

impl<'tcx, T> Eq for QueryInput<'tcx, T>

where T: Eq,

impl<'tcx, T> StructuralPartialEq for QueryInput<'tcx, T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
