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

pub type EvalToValTreeResult<'tcx> = Result<Option<ValTree<'tcx>>, ErrorHandled>;

Ok(None) indicates the constant was fine, but the valtree couldn’t be constructed. This is needed in thir::pattern::lower_inline_const.

Aliased Type

enum EvalToValTreeResult<'tcx> {
    Ok(Option<ValTree<'tcx>>),
    Err(ErrorHandled),
}

Variants

Ok(Option<ValTree<'tcx>>)

Contains the success value

Err(ErrorHandled)

Contains the error value
