}

Variants

ProjectionTy

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

InherentTy

An associated type in an inherent impl

OpaqueTy

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

WeakTy

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

UnevaluatedConst

An unevaluated const coming from a generic const expression.

ProjectionConst

An unevaluated const coming from an associated const.

Implementations

Trait Implementations

impl Clone for AliasTermKind

fn clone(&self) -> AliasTermKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AliasTermKind

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

Formats the value using the given formatter.

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

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

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

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

impl Hash for AliasTermKind

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 AliasTermKind

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

impl Ord for AliasTermKind

fn cmp(&self, other: &AliasTermKind) -> 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 AliasTermKind

fn eq(&self, other: &AliasTermKind) -> 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 AliasTermKind

fn partial_cmp(&self, other: &AliasTermKind) -> 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.

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.
