Struct Slice 

pub struct Slice {
    pub total: NonZeroU32,
    pub index: u32,
}

One of total disjoint deterministic slices of the id space.

A point belongs to the slice iff hash(id) % total == index, where hash is SipHash-2-4 with a zero key over the canonical id bytes: 8 little-endian bytes for numeric ids, the 16 RFC 4122 bytes for UUIDs. For a fixed total, slices 0..total are disjoint and together cover all points; membership is uniform regardless of the id scheme and stable across queries, segments, platforms and Qdrant versions.

Slices with different total values are correlated (same hash, no salt): e.g. slice 0 of total: 4 is a strict subset of slice 0 of total: 2. This keeps a smaller sample contained in a larger one.

Fields

total: NonZeroU32

Total number of disjoint slices the id space is split into

index: u32

Which slice to select, must be in 0..total
