Type Alias rustc_middle::mir::interpret::error::EvalToValTreeResult

source ·
pub type EvalToValTreeResult<'tcx> = Result<Result<ValTree<'tcx>, Ty<'tcx>>, ErrorHandled>;
Expand description

Ok(Err(ty)) indicates the constant was fine, but the valtree couldn’t be constructed because the value containts something of type ty that is not valtree-compatible. The caller can then show an appropriate error; the query does not have the necssary context to give good user-facing errors for this case.
