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

Unstable: age-based tier heuristic; boundaries (HOUR/DAY/WEEK) may be tuned.

• Hot (accessed in last hour): Full
• Warm (accessed in last day): Int8
• Cool (accessed in last week): Int4
• Cold (accessed in last month+): Binary

Trait Implementations

impl Clone for QuantizationTier

fn clone(&self) -> QuantizationTier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QuantizationTier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for QuantizationTier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QuantizationTier

fn cmp(&self, other: &QuantizationTier) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for QuantizationTier

fn eq(&self, other: &QuantizationTier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for QuantizationTier

fn partial_cmp(&self, other: &QuantizationTier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
