Struct EscribaHost 

pub struct EscribaHost {
    pub snapshot: EditorSnapshot,
    pub effects: Vec<HostEffect>,
}

The Lisp host: a read snapshot + an accumulating effect log. Owned (no borrows) so it satisfies Interpreter<H>’s H: 'static; passed by &mut per eval call.

Fields

snapshot: EditorSnapshot

effects: Vec<HostEffect>

pub fn take_effects(&mut self) -> Vec<HostEffect>
