Enum rustc_type_ir::AliasTyKind

pub enum AliasTyKind {
    Projection,
    Inherent,
    Opaque,
    Weak,
}

Variants

Projection

A projection <Type as Trait>::AssocType. Can get normalized away if monomorphic enough.

Inherent

An associated type in an inherent impl

Opaque

An opaque type (usually from impl Trait in type aliases or function return types) Can only be normalized away in RevealAll mode

Weak

A type alias that actually checks its trait bounds. Currently only used if the type alias references opaque types. Can always be normalized away.

Implementations

impl AliasTyKind

pub fn descr(self) -> &'static str

Trait Implementations

impl Clone for AliasTyKind

fn clone(&self) -> AliasTyKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AliasTyKind

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for AliasTyKind

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

impl<__E: SpanEncoder> Encodable<__E> for AliasTyKind

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

impl Hash for AliasTyKind

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<__CTX> HashStable<__CTX> for AliasTyKind

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

impl Ord for AliasTyKind

fn cmp(&self, other: &AliasTyKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for AliasTyKind

fn eq(&self, other: &AliasTyKind) -> 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 PartialOrd for AliasTyKind

fn partial_cmp(&self, other: &AliasTyKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<I: Interner> TypeFoldable<I> for AliasTyKind

fn try_fold_with<F: FallibleTypeFolder<I>>( self, _: &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, _: &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: Interner> TypeVisitable<I> for AliasTyKind

fn visit_with<F: TypeVisitor<I>>(&self, _: &mut F) -> F::Result

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

impl Copy for AliasTyKind

impl Eq for AliasTyKind

impl StructuralPartialEq for AliasTyKind

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.
