Struct CocoAnnotation 

pub struct CocoAnnotation {
    pub id: u64,
    pub image_id: u64,
    pub category_id: u32,
    pub bbox: [f64; 4],
    pub area: f64,
    pub iscrowd: u8,
    pub segmentation: Option<CocoSegmentation>,
}

Annotation for object detection and instance segmentation.

Each annotation represents a single object instance in an image.

Note: Keypoints, captions, and panoptic fields are NOT supported.

Fields

id: u64

Unique annotation ID.

image_id: u64

ID of the image containing this object.

category_id: u32

Category ID of this object.

bbox: [f64; 4]

Bounding box: [x, y, width, height] in pixels (top-left corner).

area: f64

Area of the segmentation mask in pixels².

iscrowd: u8

Whether this is a crowd annotation (0 = single instance, 1 = crowd).

segmentation: Option<CocoSegmentation>

Segmentation mask (polygon or RLE format).
