Type Alias rustc_middle::ty::solve::QueryResult

source ·
pub type QueryResult<I> = Result<Canonical<I, Response<I>>, NoSolution>;
Expand description

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>>),



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

Contains the success value



Contains the error value


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