Module nl

Structs§

nl: Number lines and write to the provided writer.
nl_stream_with_state: Stream nl output directly to a file descriptor in batched writes. This is the preferred entry point for the binary — avoids building the entire output in memory and instead flushes ~1MB chunks. For large files this dramatically reduces memory usage and write() syscall overhead.
nl_to_vec: Build the nl output into a Vec.
nl_to_vec_with_state: Build the nl output into a Vec, continuing numbering from line_number. Updates line_number in place so callers can continue across multiple files.
parse_number_format: Parse a number format string.
parse_numbering_style: Parse a numbering style string.
