Variants

F16 = 1

16-bit IEEE 754 half-precision float.

BF16 = 2

Brain floating point (bfloat16).

I8 = 3

Signed 8-bit integer (scalar quantized).

U8 = 4

Unsigned 8-bit integer.

I4 = 5

4-bit integer (packed, 2 per byte).

Binary = 6

1-bit binary (packed, 8 per byte).

PQ = 7

Custom = 8

Custom encoding (see QUANT_SEG for details).

Implementations

impl DataType

pub const fn bits_per_element(self) -> Option<u32>

Returns the number of bits per element, or None for variable-width types.

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataType

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

Formats the value using the given formatter.

impl Hash for DataType

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 PartialEq for DataType

fn eq(&self, other: &DataType) -> 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 TryFrom<u8> for DataType

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for DataType

impl Eq for DataType

impl StructuralPartialEq for DataType
