Module tac 

Functions

tac_bytes

Reverse records separated by a single byte. Uses forward SIMD scan (memchr_iter) to collect separator positions, then builds IoSlice references in reverse order for zero-copy writev output. No output buffer allocation — references mmap’d data directly.

tac_regex_separator

Reverse records using a regex separator.

tac_string_separator

Reverse records using a multi-byte string separator. Uses SIMD-accelerated memmem for substring search + IoSlice/writev output.
