Trait CanvasStore 

pub trait CanvasStore: Send + Sync {
    // Required methods
    fn load(&self) -> Option<Canvas>;
    fn save(&mut self, canvas: &Canvas);
}

Persistence boundary for the canonical canvas. In-memory by default; the late-sh integration plan describes a postgres-backed impl.

Required Methods

fn load(&self) -> Option<Canvas>

Called on server startup. Return the canvas to initialize with, or None for a fresh empty canvas.

fn save(&mut self, canvas: &Canvas)

Called after every applied op. Implementations may debounce or skip.
