Struct ButtonClient 

pub struct ButtonClient { /* private fields */ }

ctx.buttons — front-panel presses.

The on-device input surface for a plugin whose operator has no screen and no ground station. The host owns the bus and the short/long decode, so a plugin never re-implements debounce or the action mapping and cannot drift from what the panel’s own UI thinks a press means.

Read-only and non-exclusive: several consumers watch the same bus, so subscribing observes presses without consuming or remapping them.

Implementations

impl ButtonClient

pub async fn subscribe( &self, callback: Arc<dyn Fn(ButtonPress) + Send + Sync>, ) -> Result<(), ClientError>

Receive every front-panel press.

The callback gets the decoded ados_protocol::buttons::ButtonPress. action is None for an unmapped button — the press is still delivered, so a plugin can bind one the operator has not assigned.

A board with no front panel never fires the callback. That is the resting state, not an error, so this does not fail on a node without buttons.

Trait Implementations

impl Clone for ButtonClient

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)
