Struct ExpertLoraLayer 

pub struct ExpertLoraLayer {
    pub pairs: BTreeMap<(u16, ExpertProj), LoraPair>,
}

One MoE layer’s routed-expert LoRA coverage: a SPARSE map keyed by (expert_index, projection). Real adapters adapt a subset of the (up to 512) experts, so a dense Vec<[LoraPair; 3]> sized num_experts would waste storage and force a 512-wide static walk; the map only holds the packed pairs. LoraPair is Copy, so the whole struct is cheap to Clone on install.

Fields

pairs: BTreeMap<(u16, ExpertProj), LoraPair>

Implementations

impl ExpertLoraLayer

pub fn pair(&self, expert: u16, proj: ExpertProj) -> Option<&LoraPair>

This layer’s (expert, proj) pair, if adapted.

pub fn adapted_experts(&self) -> Vec<u16>

Sorted, deduped list of the expert indices this layer adapts — the SSOT for “which experts get a delta applied” in the forward side-path.

pub fn is_empty(&self) -> bool
