Struct DsaDims 

pub struct DsaDims {
    pub hidden: usize,
    pub index_heads: usize,
    pub index_head_dim: usize,
    pub index_kpool: usize,
    pub index_topk: usize,

}

Indexer + MLA geometry, read from the checkpoint config — never defaulted.

Fields

hidden: usize

index_heads: usize

Indexer heads (index_n_heads), NOT the MLA head count.

index_head_dim: usize

Indexer head dim (index_head_dim), NOT the MLA head dim.

index_kpool: usize

index_topk: usize

always_select_tail: bool

q_lora_rank: usize

heads: usize

kv_lora_rank: usize

qk_nope_head_dim: usize

qk_rope_head_dim: usize

Zero on GLM-5.3-Flash. Kept explicit so a nonzero value is a loud change.

v_head_dim: usize

Implementations

impl DsaDims

pub fn qk_head_dim(&self) -> usize

pub fn select_k(&self, n_pools: usize) -> usize

Pools selected per query: index_topk / index_kpool, capped by how many pools exist.

pub fn out_width(&self) -> usize

Width of the emitted index row. The tail adds kpool - 1 slots.

pub fn is_nope(&self) -> bool
