Trait Implementations

impl<'tcx> ArenaAllocatable<'tcx> for PredefinedOpaquesData<TyCtxt<'tcx>>

fn allocate_on<'a>( self, arena: &'a Arena<'tcx>, ) -> &'a mut PredefinedOpaquesData<TyCtxt<'tcx>>

fn allocate_from_iter<'a>( arena: &'a Arena<'tcx>, iter: impl IntoIterator<Item = PredefinedOpaquesData<TyCtxt<'tcx>>>, ) -> &'a mut [PredefinedOpaquesData<TyCtxt<'tcx>>]

impl<I> Clone for PredefinedOpaquesData<I>

where I: Interner,

fn clone(&self) -> PredefinedOpaquesData<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for PredefinedOpaquesData<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I, __D> Decodable<__D> for PredefinedOpaquesData<I>

where I: Interner, __D: TyDecoder<I = I>, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: Decodable<__D>,

fn decode(__decoder: &mut __D) -> PredefinedOpaquesData<I>

impl<I> Default for PredefinedOpaquesData<I>

where I: Interner,

fn default() -> PredefinedOpaquesData<I>

Returns the “default value” for a type.

impl<I, __E> Encodable<__E> for PredefinedOpaquesData<I>

where I: Interner, __E: TyEncoder<I = I>, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: Encodable<__E>,

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

impl<I> Hash for PredefinedOpaquesData<I>

where I: Interner,

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<I, __CTX> HashStable<__CTX> for PredefinedOpaquesData<I>

where I: Interner, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: HashStable<__CTX>,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl<I> PartialEq for PredefinedOpaquesData<I>

where I: Interner,

fn eq(&self, __other: &PredefinedOpaquesData<I>) -> 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 PredefinedOpaquesData<I>

where I: Interner, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: TypeFoldable<I>,

fn try_fold_with<__F>( self, __folder: &mut __F, ) -> Result<PredefinedOpaquesData<I>, <__F as FallibleTypeFolder<I>>::Error>

where __F: FallibleTypeFolder<I>,

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<I> TypeVisitable<I> for PredefinedOpaquesData<I>

where I: Interner, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: TypeVisitable<I>,

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

where __V: TypeVisitor<I>,

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

impl<I> Eq for PredefinedOpaquesData<I>

where I: Interner,

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.
