Implementations

impl QuantizationBits

pub fn to_u8(self) -> u8

Convert to number of bits

pub fn levels(self) -> usize

Get number of quantization levels (2^bits)

pub fn compression_ratio(self) -> f32

Get compression ratio vs f32 (32 bits / bits_per_dim)

pub fn values_per_byte(self) -> usize

Get number of values that fit in one byte

Trait Implementations

impl Clone for QuantizationBits

fn clone(&self) -> QuantizationBits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantizationBits

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QuantizationBits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for QuantizationBits

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

Formats the value using the given formatter.

impl PartialEq for QuantizationBits

fn eq(&self, other: &QuantizationBits) -> 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 Serialize for QuantizationBits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for QuantizationBits

impl Eq for QuantizationBits
