Struct rustc_infer::infer::type_variable::TyVidEqKey
source · pub(crate) struct TyVidEqKey<'tcx> {
vid: TyVid,
phantom: PhantomData<TypeVariableValue<'tcx>>,
}
Expand description
These structs (a newtyped TyVid) are used as the unification key
for the eq_relations
; they carry a TypeVariableValue
along
with them.

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.
