Struct DetectionBatch 

pub struct DetectionBatch {
    pub v: u16,
    pub model_id: String,
    pub camera_id: String,
    pub frame_id: u64,
    pub ts_ms: i64,
    pub frame_width: u32,
    pub frame_height: u32,
    pub detections: Vec<Detection>,
}

The payload on vision.detection, labelled by source model and frame so overlays and consumers can align boxes to the frame they came from.

Fields

v: u16

Wire version, stamped on every batch and checked on decode. A consumer that sees a version it does not speak rejects the batch instead of mis-parsing it. Deliberately carries no serde default: a payload missing this field fails to decode.

model_id: String

camera_id: String

frame_id: u64

ts_ms: i64

Capture time of the source frame: the frame’s host CLOCK_MONOTONIC timestamp in milliseconds (FrameDescriptor::ts_ns / 1_000_000).

frame_width: u32

The source frame’s pixel size, so a consumer scales the pixel-space boxes to the rendered frame. 0 when the source did not report it (the consumer then falls back to its own default). Additive + serde-default, so a batch from an older producer (no dims) still decodes (mirrors attributes).

frame_height: u32

detections: Vec<Detection>

Implementations

impl DetectionBatch

pub fn to_msgpack(&self) -> Result<Vec<u8>, Error>

pub fn from_msgpack(bytes: &[u8]) -> Result<Self, DetectionBatchError>

Decode from a msgpack map, rejecting a batch whose wire version this build does not speak. A missing v field fails the msgpack decode; a present-but-unknown v returns DetectionBatchError::Version.
