Function fulfill_or_allowed 

pub fn fulfill_or_allowed(
    cx: &LateContext<'_>,
    lint: &'static Lint,
    ids: impl IntoIterator<Item = HirId>,
) -> bool

Returns true if the lint is #[allow]ed or #[expect]ed at any of the ids, fulfilling all of the expectations in ids

This should only be used when the lint would otherwise be emitted, for a way to check if a lint is allowed early to skip work see is_lint_allowed

To emit at a lint at a different context than the one current see span_lint_hir or span_lint_hir_and_then
