Struct rustc_trait_selection::infer::canonical::CanonicalVarValues

source · [−]
pub struct CanonicalVarValues<'tcx> {
    pub var_values: IndexVec<BoundVar, GenericArg<'tcx>>,
}
Expand description

A set of values corresponding to the canonical variables from some Canonical. You can give these values to canonical_value.substitute to substitute them into the canonical value at the right places.

When you canonicalize a value V, you get back one of these vectors with the original values that were replaced by canonical variables. You will need to supply it later to instantiate the canonicalized query response.

Fields

var_values: IndexVec<BoundVar, GenericArg<'tcx>>

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.
