Type Alias rustc_type_ir::solve::QueryResult

pub type QueryResult<I> = Result<CanonicalResponse<I>, NoSolution>;

The result of evaluating a canonical query.

FIXME: We use a different type than the existing canonical queries. This is because we need to add a Certainty for overflow and may want to restructure this code without having to worry about changes to currently used code. Once we’ve made progress on this solver, merge the two responses again.

Aliased Type

enum QueryResult<I> {
    Ok(Canonical<I, Response<I>>),
    Err(NoSolution),
}

Variants

Ok(Canonical<I, Response<I>>)

Contains the success value

Err(NoSolution)

Contains the error value

Note: Encountered an error during type layout; the type failed to be normalized.
