Struct DraftFixed 

pub struct DraftFixed {
    pub embed: DevicePtr,
    pub meta: AttnMetadataDev,
    pub k_pool: DevicePtr,
    pub v_pool: DevicePtr,
    pub block_size: u32,
    pub cache_stride: u64,
    pub vocab: u32,

}

2026-09-29: The MTP draft head’s fixed buffers.

Fields

embed: DevicePtr

2026-09-29: Where the host puts the token’s embedding row (MtpHead::forward_one’s ssm_qkvz).

meta: AttnMetadataDev

2026-09-29: The draft step’s attention metadata (mtp_meta::mtp_attn_meta_dev); max_blocks_per_seq is ignored.

k_pool: DevicePtr

2026-09-29: The draft cache’s pools and geometry.

v_pool: DevicePtr

block_size: u32

cache_stride: u64

vocab: u32

2026-09-29: The vocabulary rows the draft lm_head scores (DraftBinding::vocab).

rows: Option<DraftRows>

2026-09-30: The head’s n-row draft (the batched propose) facts (DraftBinding::rows); None when the head drafts one row at a time.

Implementations

impl DraftFixed

pub fn meta_rows(&self, n: u64) -> Result<AttnMetadataDev>

2026-09-30: The attention metadata an n-row draft step uploads: the batched propose’s, at its allocation (mtp_meta::mtp_attn_meta_batch_dev); one row reads the single-row step’s.

Trait Implementations
