Struct rustc_infer::infer::TypeTrace
source · pub struct TypeTrace<'tcx> {
pub cause: ObligationCause<'tcx>,
pub 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.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
