Type Alias CanonicalUserType

pub type CanonicalUserType<'tcx> = Canonical<'tcx, UserType<'tcx>>;

Canonical user type annotation.

Aliased Type

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

Fields

value: UserType<'tcx>

max_universe: UniverseIndex

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.

Layout

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.
