Enum MoeLoraRoute 

pub enum MoeLoraRoute {
    Fold,
    Skip,
    Refuse,
}

Feature-1 MoE-LoRA fold decision for a single forward pass.

The MoE router/expert delta is a SINGLE globally-installed adapter (phase 1): this gate makes the prefill fold per-request without a device kernel, exactly mirroring the attention BGMV seq_slot < 0 skip but at request granularity. A base request pays nothing; a packed/mixed batch refuses loudly rather than fold one adapter onto every row (the device-side per-row fold that would let a mixed batch skip base rows individually is the documented follow-up — docs/design/lora-solid.md Incr 1/3).

Variants

Fold

Single-request pass whose request owns the installed active MoE adapter: FOLD. Genuine single-seq decode now folds the router + expert gate/up/down deltas at this altitude (mirroring prefill); the remaining back-compat paths (multi-seq / verify) still bail via reject_decode_lora before the fold, so their Fold value is inert there. Also the default.

Skip

Single-request pass that is base (adapter_slot < 0, no adapter) or routes to a different, non-installed adapter: SKIP the fold entirely. Base tokens pay nothing (request-granularity mirror of the attention BGMV seq_slot < 0 early-return).

Refuse

Multi-request / packed / codispatch batch whose per-row adapter identity cannot be honored without the device-side per-row fold (follow-up): the fold REFUSES loudly rather than mis-apply one adapter to every row.

Trait Implementations

impl Clone for MoeLoraRoute

fn clone(&self) -> MoeLoraRoute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MoeLoraRoute

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

Formats the value using the given formatter.

impl Default for MoeLoraRoute

fn default() -> MoeLoraRoute

Returns the “default value” for a type.

impl PartialEq for MoeLoraRoute

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