Trait rustc_const_eval::transform::check_consts::ops::NonConstOp

pub trait NonConstOp<'tcx>: Debug {
    // Required method
    fn build_error(&self, ccx: &ConstCx<'_, 'tcx>, span: Span) -> Diag<'tcx>;

    // Provided methods
    fn status_in_item(&self, _ccx: &ConstCx<'_, 'tcx>) -> Status { ... }
    fn importance(&self) -> DiagImportance { ... }
}

An operation that is not always allowed in a const context.

Required Methods

fn build_error(&self, ccx: &ConstCx<'_, 'tcx>, span: Span) -> Diag<'tcx>

Provided Methods

fn status_in_item(&self, _ccx: &ConstCx<'_, 'tcx>) -> Status

Returns an enum indicating whether this operation is allowed within the given item.

fn importance(&self) -> DiagImportance
