Functions§

tac_bytes
Reverse the records in data separated by a single byte separator and write to out. If before is true, the separator is attached before the record instead of after. Uses forward memchr scan for SIMD-accelerated separator finding with optimal prefetch.
tac_regex_separator
Reverse records using a regex separator. Uses regex::bytes for direct byte-level matching (no UTF-8 conversion needed). NOTE: GNU tac uses POSIX Basic Regular Expressions (BRE), so we convert to ERE first. Uses backward scanning to match GNU tac’s re_search behavior.
tac_string_separator
Reverse records using a multi-byte string separator. Uses SIMD-accelerated memmem for substring search.
