Struct CameraClient 

pub struct CameraClient { /* private fields */ }

ctx.camera — path-level claim/release, a frame-pull primitive, and the exposure and gain of cameras the vision engine owns.

Implementations

impl CameraClient

pub async fn claim( &self, device_path: &str, exclusive: bool, ) -> Result<Value, ClientError>

Claim a /dev/videoN path. A second exclusive claim on the same path is refused before any V4L2 handle is opened.

pub async fn release(&self, device_path: &str) -> Result<Value, ClientError>

Release a claimed camera path.

pub async fn get_frame( &self, device_path: &str, format: &str, timeout_ms: i64, ) -> Result<Value, ClientError>

Pull the latest captured frame. The result map carries frame_id, width, height, format, data, ts_ns, stale. Repeated stale frames signal a stalled capture pipeline.

pub async fn set_controls( &self, req: &CameraControlRequest, ) -> Result<CameraControlResult, ClientError>

Set exposure, gain or auto exposure on the engine-owned camera req.camera_id and return the values it reads back. Needs camera.control.write. See PluginIpcClient::camera_set_controls.

Trait Implementations

impl Clone for CameraClient

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
