Enum ra_ap_hir_ty::AliasTy

pub enum AliasTy {
    Projection(ProjectionTy),
    Opaque(OpaqueTy),
}

Variants

Projection(ProjectionTy)

A “projection” type corresponds to an (unnormalized) projection like <P0 as Trait<P1..Pn>>::Foo. Note that the trait and all its parameters are fully known.

Opaque(OpaqueTy)

An opaque type (impl Trait).

This is currently only used for return type impl trait; each instance of impl Trait in a return type gets its own ID.

Trait Implementations
