Struct SpillBlock 

pub struct SpillBlock {
    pub host: HostBuf,
    pub qtype: i32,
    pub in_f: usize,
    pub out_f: usize,
    pub row_bytes: usize,
}

SPILLING-PLAN §3/§5: a single spillable weight block over the same {Pinned, Mmap} substrate. Lifted from the HostExps fields so dense weights (dense-70B case) can reuse the disk tier without the 256-expert stacking. Carried for the requested generalization; the MoE path uses HostExps directly (which now embeds the same tier machinery via HostBuf).

Fields

host: HostBuf

qtype: i32

in_f: usize

out_f: usize

row_bytes: usize

Implementations

impl SpillBlock

pub fn bytes(&self) -> &[u8]

The H2D DMA source for this block — resolves the tier (Pinned fast / Mmap demand-fault).
