Enum DType 

#[repr(u8)]
pub enum DType {
    F16 = 0,
    BF16 = 1,
    F32 = 2,
    F64 = 3,
    I32 = 4,
    I64 = 5,
    U8 = 6,
    Bool = 7,
}

Supported tensor data types

Volta internally uses a byte buffer + dtype tag approach, allowing runtime flexibility for mixed-precision operations and easy loading of external model formats.

Variants

F16 = 0

16-bit floating point (IEEE 754 half precision)

BF16 = 1

16-bit brain floating point (truncated f32 mantissa)

F32 = 2

32-bit floating point (default)

F64 = 3

64-bit floating point

I32 = 4

32-bit signed integer

I64 = 5

64-bit signed integer

U8 = 6

8-bit unsigned integer

Bool = 7

Boolean (stored as u8)

Implementations

impl DType

pub fn size_of(&self) -> usize

Returns the size in bytes of a single element of this dtype

pub fn name(&self) -> &'static str

Returns the name of this dtype as a string

pub fn is_float(&self) -> bool

Returns true if this is a floating-point type

pub fn is_int(&self) -> bool

Returns true if this is an integer type

pub fn promote(a: DType, b: DType) -> DType

Determines the result dtype when two dtypes are combined in an operation. Follows type promotion rules similar to PyTorch/NumPy.

Trait Implementations

impl Clone for DType

fn clone(&self) -> DType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DType

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

Formats the value using the given formatter.

impl Default for DType

fn default() -> DType

Returns the “default value” for a type.

impl Display for DType

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

Formats the value using the given formatter.

impl Hash for DType

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 DType

fn eq(&self, other: &DType) -> 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 Copy for DType
