Type Alias OnLinesArgs 

pub type OnLinesArgs = (String, Buffer, u32, usize, usize, usize, usize, Option<usize>, Option<usize>);

Arguments passed to the callback registered to on_lines. The (a, b, c, d, e, f, g, h, i) tuple represents:

• a: the string literal "lines";
• b: the Buffer that triggered the callback;
• c: the value of the buffer-local b:changedtick variable;
• d: first row that changed (0-indexed);
• e: last row that was changed;
• f: last row in the updated range;
• g: byte count of previous contents;
• h: deleted UTF-32 codepoints (if utf_sizes was true);
• i: deleted UTF-16 codeunits (if utf_sizes was true);
