Function rustc_traits::type_op_prove_predicate_with_cause

pub fn type_op_prove_predicate_with_cause<'tcx>(
    ocx: &ObligationCtxt<'_, 'tcx>,
    key: ParamEnvAnd<'tcx, ProvePredicate<'tcx>>,
    cause: ObligationCause<'tcx>
)

The core of the type_op_prove_predicate query: for diagnostics purposes in NLL HRTB errors, this query can be re-run to better track the span of the obligation cause, and improve the error message. Do not call directly unless you’re in that very specific context.
