Enum UserTypeKind

pub enum UserTypeKind<'tcx> {
    Ty(Ty<'tcx>),
    TypeOf(DefId, UserArgs<'tcx>),
}

A user-given type annotation attached to a constant. These arise from constants that are named via paths, like Foo::<A>::new and so forth.

Variants

Ty(Ty<'tcx>)

TypeOf(DefId, UserArgs<'tcx>)

The canonical type is the result of type_of(def_id) with the given generic parameters applied.

Trait Implementations

impl<'tcx> Clone for UserTypeKind<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for UserTypeKind<'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 UserTypeKind<'tcx>

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

impl<'tcx> Display for UserTypeKind<'tcx>

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

Formats the value using the given formatter.

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

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

impl<'tcx> Hash for UserTypeKind<'tcx>

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<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for UserTypeKind<'tcx>

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

impl<'tcx> PartialEq for UserTypeKind<'tcx>

fn eq(&self, other: &UserTypeKind<'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<'tcx> TypeFoldable<TyCtxt<'tcx>> for UserTypeKind<'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) -> 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> TypeVisitable<TyCtxt<'tcx>> for UserTypeKind<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &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<'tcx> Copy for UserTypeKind<'tcx>

impl<'tcx> Eq for UserTypeKind<'tcx>

impl<'tcx> StructuralPartialEq for UserTypeKind<'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.
