pub struct Canonical<'tcx, V> {
    pub max_universe: UniverseIndex,
    pub variables: &List<CanonicalVarInfo>,
    pub value: V,
}

Expand description

A “canonicalized” type V is one where all free inference variables have been rewritten to “canonical vars”. These are numbered starting from 0 in order of first appearance.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
