pub fn find_ascii_case_insensitive_from(
text: &str,
needle: &str,
start: usize,
) -> Option<usize>Expand description
Find an ASCII needle at or after byte offset start in text.
start need not be a UTF-8 character boundary because matching is performed
on bytes. A successful position is always a boundary: an ASCII needle can
only begin on an ASCII byte in the original string.
