Function to_lines 

pub fn to_lines(payload: &str) -> Vec<String>

Split a payload into its lines for line-anchored matching. A single final terminating newline ends the last line — it does not add an empty trailing line. A trailing \r on each line is dropped, so a CRLF-terminated payload (e.g. an anchor file saved by a Windows editor) matches LF source. An empty payload has zero lines.

Examples

use coding_tools::payload::to_lines;

assert_eq!(to_lines("foo\n"), vec!["foo"]);          // final newline ends the line
assert_eq!(to_lines("a\nb"), vec!["a", "b"]);
assert_eq!(to_lines("a\n\n"), vec!["a", ""]);        // an intentional blank line stays
assert_eq!(to_lines("a\r\nb\r\n"), vec!["a", "b"]);  // CRLF normalized to LF
assert!(to_lines("").is_empty());                     // empty payload: zero lines
