Struct W4a16BatchmTiers 

pub struct W4a16BatchmTiers { /* private fields */ }

Resolved handles for the narrow w4a16_gemv_batch{M} family.

A zero handle means “this target did not load that tier”; every consumer must gate on .0 != 0 exactly as it did with the individual fields, and Self::kernel returns a zero handle rather than panicking when nothing in the family covers m.

Implementations

impl W4a16BatchmTiers

pub fn resolve(gpu: &dyn GpuBackend) -> Self

Resolve every tier in the family. Misses are silent zero handles — tiers 5/6/7 are absent from any target built before they existed, and dispatch degrades to the pre-existing batch4/batch8 decision.

pub fn kernel(&self, m: u32) -> KernelHandle

Narrowest resolved tier covering m rows, or KernelHandle(0) when this family cannot serve m.

pub fn width(&self, m: u32) -> Option<u32>

Width of the tier Self::kernel would pick, for logging and tests.

pub fn has_base(&self) -> bool

Is the BASE (w4a16_gemv_batch4) tier resolved? Capability probes that ask “can this build do NVFP4 batched decode at all” mean this one specifically — it is the tier every target has carried.

Trait Implementations

impl Clone for W4a16BatchmTiers

fn clone(&self) -> W4a16BatchmTiers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for W4a16BatchmTiers

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

Formats the value using the given formatter.

impl Default for W4a16BatchmTiers

KernelHandle has no Default, so the “no NVFP4 kernels” state is spelled out: an all-zero table, which every consumer already treats as “decline”.

fn default() -> Self

Returns the “default value” for a type.
