Fields

vid: EffectVid

phantom: PhantomData<Const<'tcx>>

Trait Implementations

impl<'tcx> Clone for EffectVidKey<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for EffectVidKey<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> From<EffectVid> for EffectVidKey<'tcx>

fn from(vid: EffectVid) -> Self

Converts to this type from the input type.

impl<'tcx> PartialEq for EffectVidKey<'tcx>

fn eq(&self, other: &EffectVidKey<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> UnifyKey for EffectVidKey<'tcx>

type Value = EffectVarValue<'tcx>

fn index(&self) -> u32

fn from_index(i: u32) -> Self

fn tag() -> &'static str

fn order_roots( a: Self, a_value: &Self::Value, b: Self, b_value: &Self::Value ) -> Option<(Self, Self)>

You should return first the key that should be used as root, then the other key (that will then point to the new root).

impl<'tcx> Copy for EffectVidKey<'tcx>

impl<'tcx> StructuralPartialEq for EffectVidKey<'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.
