Struct TelemetryClient 

pub struct TelemetryClient { /* private fields */ }

ctx.telemetry — read the vehicle state and extend the heartbeat schema.

Implementations

impl TelemetryClient

pub async fn subscribe( &self, callback: EventCallback, ) -> Result<(), ClientError>

Receive the vehicle-state snapshot (armed, mode, position, attitude, battery, …), the newest at most ten times a second. The callback gets the state object itself, a map keyed as the agent’s state wire. A node with no flight controller never fires it. Needs telemetry.read.

pub async fn extend( &self, channel: &str, payload: Value, ) -> Result<Value, ClientError>

Add a channel of fields to the telemetry stream that ships to the GCS.

Trait Implementations

impl Clone for TelemetryClient

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
