Enum Segmentation 

pub enum Segmentation {
    Polygons(Vec<Vec<f64>>),
    Rle(SegmentationRle),
}

One COCO segmentation field, in any of the three shapes pycocotools accepts. The dataset stores this verbatim; Self::to_rle normalizes to a single Rle at eval time.

Variants

Polygons(Vec<Vec<f64>>)

Multi-polygon shape ([[x0, y0, x1, y1, …], …]). Each inner vector is a flat (x, y) pair sequence. Merged into a single RLE via union per K2.

Rle(SegmentationRle)

COCO RLE shape ({"size": [h, w], "counts": …}). Counts payload may be either the compressed 6-bit char string (typical) or an uncompressed JSON array of integers.

Implementations

impl Segmentation

pub fn to_rle(&self, h: u32, w: u32) -> Result<Rle, EvalError>

Normalizes this segmentation into a single Rle of shape (h, w).

• Polygons are rasterized via Rle::from_polygon and unioned into one RLE (K2).
• An RLE variant is checked against the requested (h, w); mismatch raises EvalError::DimensionMismatch (H2 corrected).

Trait Implementations

impl Clone for Segmentation

fn clone(&self) -> Segmentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Segmentation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Segmentation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Segmentation

fn eq(&self, other: &Segmentation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Segmentation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
