Struct rustc_next_trait_solver::solve::assembly::Candidate
source · pub(super) struct Candidate<I: Interner> {
pub(super) source: CandidateSource<I>,
pub(super) result: CanonicalResponse<I>,
}
Expand description
A candidate is a possible way to prove a goal.
It consists of both the source
, which describes how that goal would be proven,
and the result
when using the given source
.

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.
