Enum QuantizationTier 

pub enum QuantizationTier {
    Full,
    Int8,
    Int4,
    Binary,
}

Unstable: tier design is under active iteration; tier boundaries may change.

Quantization precision tier, ordered from highest to lowest fidelity.

Variants

Full

Full f32 precision (4 bytes/dim, 1x baseline).

Int8

INT8 symmetric quantization (1 byte/dim, 4x compression).

Int4

INT4 packed nibble quantization (0.5 bytes/dim, 8x compression).

Binary

Binary sign-bit quantization (0.125 bytes/dim, 32x compression).

Implementations

impl QuantizationTier

pub fn bytes_per_dim(&self) -> f32

Unstable: bytes-per-dimension constant; may change with new tiers.

pub fn compression_ratio(&self) -> f32

Unstable: compression ratio; derived from bytes_per_dim, may be removed.

pub fn storage_bytes(&self, dims: usize) -> usize

Unstable: storage byte computation; may change with new tiers.

pub fn from_age_seconds(age_secs: u64) -> Self

Warning: this is a placeholder storage policy, not evidence that older vectors tolerate lower precision. Callers should measure retrieval quality for their workload.

Unstable: tier boundaries may be tuned.
