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

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

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

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

Required Methods

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

Provided Methods

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

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