pub fn find_trailing_pragma_offset(comment: &str) -> Option<usize>Expand description
Returns the byte offset within comment where a trailing pragma comment starts,
or None if no pragma is found.
For a plain pragma like # noqa: F401, returns Some(0).
For a nested pragma like # some text # noqa: F401, returns the offset of the
trailing # that begins the pragma (i.e., the start of # noqa: F401).

assert_eq!(ruff_python_trivia::find_trailing_pragma_offset("## noqa: F401"), Some(1));
assert_eq!(ruff_python_trivia::find_trailing_pragma_offset("# just a comment"), None);
