Enum RotationBackend 

pub enum RotationBackend {
    FastHadamard(FastHadamardRotation),
    StoredQr(StoredRotation),
}

Concrete rotation backend used by quantizers.

Variants

FastHadamard(FastHadamardRotation)

StoredQr(StoredRotation)

Implementations

impl RotationBackend

pub fn new(dim: usize, seed: u64, kind: RotationKind) -> Result<Self>

pub fn kind(&self) -> RotationKind

pub fn kind_label(&self) -> &'static str

pub fn seed(&self) -> u64

impl RotationBackend

pub fn apply_inverse_batch(&self, inputs: &[&[f32]]) -> Result<Vec<Vec<f32>>>

Apply the inverse rotation to a batch of dim-sized slices in one call. For FastHadamard this is the same per-vector math as apply_inverse but amortized across the whole batch. For StoredQr the d×d matrix is converted to a row-major Vec<f32> once and reused across the batch.

Trait Implementations

impl Clone for RotationBackend

fn clone(&self) -> RotationBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RotationBackend

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RotationBackend

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Rotation for RotationBackend

fn dim(&self) -> usize

impl Serialize for RotationBackend

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
