Struct rustc_trait_selection::infer::canonical::Canonical
source · pub struct Canonical<'tcx, V> {
pub value: V,
pub max_universe: UniverseIndex,
pub variables: &'tcx List<CanonicalVarInfo<'tcx>>,
}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.
