[−][src]Enum rustc_infer::infer::canonical::CanonicalVarKind
Describes the "kind" of the canonical variable. This is a "kind" in the type-theory sense of the term -- i.e., a "meta" type system that analyzes type-like values.
Variants
Some kind of type inference variable.
PlaceholderTy(Placeholder<BoundVar>)A "placeholder" that represents "any type".
Region(UniverseIndex)Region variable '?R.
PlaceholderRegion(Placeholder<BoundRegion>)A "placeholder" that represents "any region". Created when you
are solving a goal like for<'a> T: Foo<'a> to represent the
bound region 'a.
Const(UniverseIndex)Some kind of const inference variable.
PlaceholderConst(Placeholder<BoundConst<'tcx>>)A "placeholder" that represents "any const".
