Function rustc_expand::mbe::transcribe::out_of_bounds_err

fn out_of_bounds_err<'a>(
    cx: &ExtCtxt<'a>,
    max: usize,
    span: Span,
    ty: &str
) -> Diag<'a>

Used by meta-variable expressions when an user input is out of the actual declared bounds. For example, index(999999) in an repetition of only three elements.
