Struct KernelVariant 

pub struct KernelVariant { /* private fields */ }

One concrete runtime dispatch table.

Variants are exposed so the scalar oracle, property suite, fuzzer, and future frontier harness can evaluate every arm independently of the global once-selected default.

Implementations

impl KernelVariant

pub fn scalar() -> Self

Returns the scalar oracle variant.

pub fn arm(self) -> KernelArm

Returns this variant’s runtime family.

pub fn tier(self) -> InstructionTier

Returns this variant’s precise instruction tier.

pub fn dot_i8(self, a: &[i8], b: &[i8]) -> i32

Computes an i8 dot product through this concrete table.

pub fn dot_f32(self, a: &[f32], b: &[f32]) -> f32

Computes an f32 dot product through this concrete table.

pub fn dot_f16(self, a: &[u16], b: &[u16]) -> f32

Computes an IEEE-f16-bits dot product through this concrete table.

pub fn hamming_u1(self, a: &[u8], b: &[u8]) -> u32

Computes packed-byte Hamming distance through this concrete table.

pub fn dot_i8_batch(self, q: &[i8], rows: &[i8], d: usize, out: &mut [i32])

Scores contiguous i8 rows through this concrete table.

pub fn hamming_u1_batch( self, q: &[u8], rows: &[u8], d_bytes: usize, out: &mut [u32], )

Scores contiguous packed-bit rows through this concrete table.

pub fn dot_bit4(self, q: &[i8], codes: &[u8]) -> i32

Scores a signed-byte query against one packed four-bit row.

pub fn dot_bit4_batch(self, q: &[i8], rows: &[u8], d: usize, out: &mut [i32])

Scores a signed-byte query against contiguous packed four-bit rows.

pub fn score_bit4_ptrs( &self, query: (&[i8], i32, f64), rows: &Bit4Rows4<'_>, factors: &[Bit4Factors; 4], out: &mut [f32; 4], ) -> Result<(), GatherShapeError>

Scores four arbitrary validated packed four-bit rows through this table.

Safety

Bit4Rows4::from_rows proves that every row address is readable for a common width and that the mapped regions outlive this call. This method checks that the width equals q.len().div_ceil(2) and that the supported dimension bound holds. No row alignment is required.
