Trait Implementations

impl<I> Clone for OpaqueTypeKey<I>

where I: Interner,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for OpaqueTypeKey<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I: Interner, __D: TyDecoder<I = I>> Decodable<__D> for OpaqueTypeKey<I>

where I::LocalDefId: Decodable<__D>, I::GenericArgs: Decodable<__D>,

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

impl<I: Interner, __E: TyEncoder<I = I>> Encodable<__E> for OpaqueTypeKey<I>

where I::LocalDefId: Encodable<__E>, I::GenericArgs: Encodable<__E>,

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

impl<I> Hash for OpaqueTypeKey<I>

where I: Interner,

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

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<I: Interner, __CTX> HashStable<__CTX> for OpaqueTypeKey<I>

where I::LocalDefId: HashStable<__CTX>, I::GenericArgs: HashStable<__CTX>,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl<I> PartialEq for OpaqueTypeKey<I>

where I: Interner,

fn eq(&self, __other: &Self) -> 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<I> TypeFoldable<I> for OpaqueTypeKey<I>

where I: Interner, I::LocalDefId: TypeFoldable<I>, I::GenericArgs: TypeFoldable<I>,

fn try_fold_with<__F: FallibleTypeFolder<I>>( 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: TypeFolder<I>>(self, folder: &mut F) -> Self

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<I> TypeVisitable<I> for OpaqueTypeKey<I>

where I: Interner, I::LocalDefId: TypeVisitable<I>, I::GenericArgs: TypeVisitable<I>,

fn visit_with<__V: TypeVisitor<I>>(&self, __visitor: &mut __V) -> __V::Result

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

impl<I> Copy for OpaqueTypeKey<I>

where I: Interner,

impl<I> Eq for OpaqueTypeKey<I>

where I: Interner,

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.
