Struct Update 

#[non_exhaustive]
pub struct Update {
    pub changed: bool,
    pub exit: Option<ExitDir>,
    pub close: bool,
    pub entered_host_box: Option<HostBoxEntry>,
    pub needs_redraw: bool,
    pub reminted: Vec<(u32, u32)>,
}

What one session call did, for the host to act on.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

changed: bool

The document changed.

exit: Option<ExitDir>

The caret tried to leave the formula in this direction.

close: bool

Deleting in an empty formula asks the host to end math mode.

entered_host_box: Option<HostBoxEntry>

Motion stopped in front of a host box, see Session::step_over_host_box.

needs_redraw: bool

The document, caret, selection, or menu changed, so the view should be drawn again.

reminted: Vec<(u32, u32)>

(old, new) for every host box a paste gave a fresh token, in document order.
