Function last_chord_token_byte_len 

pub fn last_chord_token_byte_len(text: &str) -> usize

Number of bytes the last chord token occupies at the end of text, treating it as a sequence of chord tokens (one chord per logical keypress). Used by chord-capture’s backspace handler to remove a whole token instead of a single char.

A token is either:

• A <…> group (matched balanced angle brackets).
• A single character.

Returns 0 if text is empty.

Examples

use lattice_protocol::last_chord_token_byte_len;

assert_eq!(last_chord_token_byte_len("gg<C-w>"), 5); // "<C-w>"
assert_eq!(last_chord_token_byte_len("<C-w>é"), 2); // one 2-byte char
assert_eq!(last_chord_token_byte_len(""), 0);
