Struct LoraLayerWeights 

pub struct LoraLayerWeights {
    pub layer_idx: usize,
    pub q_proj: Option<LoraPair>,
    pub k_proj: Option<LoraPair>,
    pub v_proj: Option<LoraPair>,
    pub o_proj: Option<LoraPair>,
    pub gate_proj: Option<LoraPair>,
    pub up_proj: Option<LoraPair>,
    pub down_proj: Option<LoraPair>,
    pub out_proj: Option<LoraPair>,
    pub router: Option<LoraPair>,
    pub experts: Option<ExpertLoraLayer>,
}

2026-09-25: One layer’s adapted modules, as LoraPairs; None means the module is not adapted. Clone because a rotation copies the new active slot’s layers out of the pool set before re-installing them.

Fields

layer_idx: usize

q_proj: Option<LoraPair>

k_proj: Option<LoraPair>

v_proj: Option<LoraPair>

o_proj: Option<LoraPair>

gate_proj: Option<LoraPair>

up_proj: Option<LoraPair>

down_proj: Option<LoraPair>

out_proj: Option<LoraPair>

router: Option<LoraPair>

2026-09-25: MoE router (mlp.gate) delta. None unless the adapter targets the router; loading such an adapter needs METRALE_LORA_EXPERTS=1.

experts: Option<ExpertLoraLayer>

2026-09-25: This layer’s routed-expert pairs. None unless the adapter carries expert deltas (which also need METRALE_LORA_EXPERTS=1). They live in LoraWeights::expert_pool, outside the equal-size slot pool.

Implementations

impl LoraLayerWeights

pub fn empty(layer_idx: usize) -> Self

2026-09-25: An entry for layer_idx with no module adapted.

impl LoraLayerWeights

pub fn module_pair(&self, module: LoraModule) -> Option<&LoraPair>

2026-09-25: This layer’s pair for module; None when the module is not adapted. select_routed_pair reads pairs through it.

Trait Implementations

impl Clone for LoraLayerWeights

fn clone(&self) -> LoraLayerWeights

Returns a duplicate of the value.

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

Performs copy-assignment from source.
