Struct rustc_infer::infer::TypeTrace

source · [−]

pub struct TypeTrace<'tcx> {
    cause: ObligationCause<'tcx>,
    values: ValuePairs<'tcx>,
}

Expand description

The trace designates the path through inference that we took to encounter an error or subtyping constraint.

See the error_reporting module for more details.
