Struct rustc_middle::infer::canonical::CanonicalVarInfo[][src]

pub struct CanonicalVarInfo<'tcx> {
    pub kind: CanonicalVarKind<'tcx>,

Information about a canonical variable that is included with the canonical value. This is sufficient information for code to create a copy of the canonical value in some other inference context, with fresh inference variables replacing the canonical values.
