Struct KernelCaps 

pub struct KernelCaps {
    pub accelerator: &'static str,
    pub min_batch: usize,
    pub max_dim: usize,
    pub deterministic: bool,
}

Capability advertisement for a vector kernel. The caller’s dispatch policy compares these against the request to pick the best kernel for a given batch + determinism requirement.

Fields

accelerator: &'static str

Symbolic accelerator label: “cpu”, “cpu-simd”, “cuda”, “metal”, “rocm”, “wasm-simd”, etc. Surfaced in stats.

min_batch: usize

Minimum batch size at which this kernel is ever chosen. CPU kernels report 1; GPU kernels typically ≥ 64.

max_dim: usize

Maximum dimensionality the kernel supports without falling back to a slower path. usize::MAX means “no constraint”.

deterministic: bool

Does the kernel produce byte-identical output (scan + rerank) vs the reference CPU kernel? Only deterministic kernels can feed witness-sealed outputs under Fresh/Frozen consistency.

Implementations

impl KernelCaps

pub const fn cpu_default() -> Self

Default CPU caps: available always, deterministic, no dim cap.

Trait Implementations

impl Clone for KernelCaps

fn clone(&self) -> KernelCaps

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KernelCaps

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

Formats the value using the given formatter.
