pub fn find_ascii_case_insensitive(text: &str, needle: &str) -> Option<usize>Expand description
Dependency-neutral byte-stable ASCII matching helpers. Re-exported here
to preserve the SQL parser’s existing public API; SQL keyword boundary and
literal-segment handling remain local to this module.
Find an ASCII needle in text without allocating a case-transformed
copy. The returned byte offset always belongs to text.
