Struct ra_ap_hir_ty::Canonical

pub struct Canonical<T> {
    pub value: T,
    pub kinds: Arc<[TyKind]>,
}

Basically a claim (currently not validated / checked) that the contained type / trait ref contains no inference variables; any inference variables it contained have been replaced by bound variables, and kinds tells us how many there are and whether they were normal or float/int variables. This is used to erase irrelevant differences between types before using them in queries.

Fields

value: T

kinds: Arc<[TyKind]>

Implementations
