Enum Msg 

pub enum Msg {
    Select(Option<String>),
    PanBy(f32, f32),
    ZoomBy(f32),
    Fit,
}

A robot-/CLI-addressable control message (FC-2) — the named boundary a headless driver (or a host) drives the pane through, the same effect a canvas click/drag/scroll produces. Applied by DecoratedGraphView::update.

Variants

Select(Option<String>)

Select a node by stable id (lights its downstream subtree), or None to clear.

PanBy(f32, f32)

Pan the camera by a screen-space delta (the drag gesture).

ZoomBy(f32)

Zoom by a scroll amount (multiplicative, clamped) — the scroll-wheel gesture.

Fit

Reset pan + zoom (the ⊙ fit affordance).
