Enum HcVariant 

pub enum HcVariant {
    Sinkhorn,
    LowRank,
}

2026-09-25: Which family a site’s weights select. Callers use it to decide whether the block’s input_norm runs on hc_pre’s output (HcVariant::applies_block_input_norm): in the low-rank family hc_norm inside hc_pre is the block’s input norm, and a second RMS pass with a ones-filled weight is not an identity.

Variants

Sinkhorn

2026-09-25: DeepSeek-V4: Sinkhorn mix, [hc, hc] combine matrix.

LowRank

2026-09-25: Qwen3.8-Flash-Next: low-rank pair, one injection scalar per stream.

Implementations

impl HcVariant

pub fn of_site(site: &HcSiteWeights) -> Self

pub fn of(hc: &HcWeights) -> Self

pub fn applies_block_input_norm(self) -> bool

2026-09-25: Whether the block’s own input_norm runs on hc_pre’s output: true only for HcVariant::Sinkhorn.

Trait Implementations

impl Clone for HcVariant

fn clone(&self) -> HcVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HcVariant

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

Formats the value using the given formatter.

impl PartialEq for HcVariant

fn eq(&self, other: &HcVariant) -> 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.
