Struct rustc_trait_selection::infer::canonical::QueryResponse[−][src]

pub struct QueryResponse<'tcx, R> {
    pub var_values: CanonicalVarValues<'tcx>,
    pub region_constraints: QueryRegionConstraints<'tcx>,
    pub certainty: Certainty,
    pub value: R,
}

Expand description

After we execute a query with a canonicalized key, we get back a Canonical<QueryResponse<..>>. You can use instantiate_query_result to access the data in this result.

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.
