Struct ScanDispatchScratch 

pub struct ScanDispatchScratch {
    pub haystack_bytes: Vec<u8>,
    pub hit_bytes: Vec<u8>,
}

Reusable host-side staging for scan dispatches.

Engines that repeatedly scan many haystacks can keep one scratch value per worker thread and pass it through *_with_scratch APIs. This removes the fixed haystack-packing allocation from every dispatch while preserving the same borrowed-input backend contract.

Fields

haystack_bytes: Vec<u8>

Packed little-endian u32 haystack bytes.

hit_bytes: Vec<u8>

Optional zeroed hit-buffer staging used by single-buffer hit layouts.
