pub fn can_append(&self, text: &str, add_space: bool) -> bool

Whether text fits at the end, after a space where asked: music21’s canAppend.

pub fn can_insert(&self, location: usize, text: &str) -> bool

Whether text fits from a cell on: music21’s canInsert.

pub fn last_hyphen_to_space(&mut self)

Takes back a music hyphen ending the line: music21’s lastHyphenToSpace.

pub fn text(&self) -> String
