Enum InferConst

pub enum InferConst {
    Var(ConstVid),
    EffectVar(EffectVid),
    Fresh(u32),
}

An inference variable for a const, for use in const generics.

Variants

Var(ConstVid)

Infer the value of the const.

EffectVar(EffectVid)

Infer the value of the effect.

For why this is separate from the Var variant above, see the documentation on EffectVid.

Fresh(u32)

A fresh const variable. See infer::freshen for more details.

Trait Implementations

impl Clone for InferConst

fn clone(&self) -> InferConst

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InferConst

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

Formats the value using the given formatter.

impl<__D> Decodable<__D> for InferConst

where __D: TyDecoder,

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

impl<__E> Encodable<__E> for InferConst

where __E: TyEncoder,

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

impl Hash for InferConst

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<CTX> HashStable<CTX> for InferConst

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher<SipHasher128>)

impl Ord for InferConst

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

Restrict a value to a certain interval.

impl PartialEq for InferConst

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

fn partial_cmp(&self, other: &InferConst) -> 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<'tcx> TypeFoldable<TyCtxt<'tcx>> for InferConst

fn try_fold_with<F>( self, _folder: &mut F, ) -> Result<InferConst, <F as FallibleTypeFolder<TyCtxt<'tcx>>>::Error>

where F: FallibleTypeFolder<TyCtxt<'tcx>>,

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 InferConst

fn visit_with<V>( &self, _visitor: &mut V, ) -> <V as TypeVisitor<TyCtxt<'tcx>>>::Result

where V: TypeVisitor<TyCtxt<'tcx>>,

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

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.
