Canonical user type annotation.

Aliased Type§

struct CanonicalUserType<'tcx> {
    pub value: UserType<'tcx>,
    pub max_universe: UniverseIndex,
    pub defining_opaque_types: &'tcx RawList<(), LocalDefId>,
    pub variables: &'tcx RawList<(), CanonicalVarInfo<TyCtxt<'tcx>>>,

Trait Implementations§


impl<'tcx> IsIdentity for CanonicalUserType<'tcx>


fn is_identity(&self) -> bool

Returns true if this represents the generic parameters of the form [?0, ?1, ?2], i.e., each thing is mapped to a canonical variable with the same index.
