Enum QuantScheme 

#[repr(u8)]
pub enum QuantScheme {
    F32 = 0,
    F16 = 1,
    Int8 = 2,
    Bit4 = 4,
}

Persisted quantization scheme identifier.

Discriminants are an append-only storage contract. They must never be reordered, renumbered, or reused. Ids 3 and 5 are retired and permanently reserved by docs/adr/ADR-002-retire-bit1-bit2.md.

Variants

F32 = 0

Uncompressed IEEE binary32 coordinates.

F16 = 1

IEEE binary16 coordinates.

Int8 = 2

Signed eight-bit scalar quantization.

Bit4 = 4

Four-bit Extended-RaBitQ codes.
