Enum KernelKind 

pub enum KernelKind {
    Bbox,
    Segm,
    Boundary,
    Keypoints,
}

Discriminator for the four kernel families on the IoU axis (per ADR-0012’s iou-type taxonomy). Carried in distributed-eval partials (ADR-0031) so a head-rank reconstruction refuses to merge bbox and segm partials silently.

Variant order is wire-format load-bearing: the rkyv archived discriminant is keyed off it. Adding new kernels appends; never reorder, never remove. Use a new ADR + format-version bump if the space ever needs to change.

Variants

Bbox

BboxIou — axis-aligned box IoU (the default).

Segm

SegmIou (and SegmIouCached) — RLE/polygon mask IoU.

Boundary

BoundaryIou (and BoundaryIouCached) — boundary-IoU per ADR-0017.

Keypoints

OksSimilarity — OKS-based keypoints similarity (ADR-0012).

Implementations

impl KernelKind

pub const fn discriminator(self) -> u32

u32 discriminator carried in the wire envelope header (ADR-0032). Stable values: Bbox=0, Segm=1, Boundary=2, Keypoints=3 — the same values ADR-0031 wrote as a u8. Adding new kernels appends; never reorder.

Trait Implementations

impl Archive for KernelKind

type Archived = ArchivedKernelKind

The archived representation of this type.

type Resolver = KernelKindResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for KernelKind

fn clone(&self) -> KernelKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KernelKind

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<KernelKind, __D> for Archived<KernelKind>

fn deserialize( &self, deserializer: &mut __D, ) -> Result<KernelKind, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Hash for KernelKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KernelKind

fn eq(&self, other: &KernelKind) -> 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<__S: Fallible + ?Sized> Serialize<__S> for KernelKind

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for KernelKind

impl Eq for KernelKind

impl StructuralPartialEq for KernelKind
