Enum DType 

Source
pub enum DType {
    F64,
    F32,
    I64,
    I32,

    Bool,
    Bf16,

    Complex,
}
Expand description

Element type for typed tensor storage.

Each variant determines how the raw byte buffer is interpreted. Byte widths are fixed and platform-independent (little-endian canonical).

Variants§

§

F64

64-bit IEEE 754 float (8 bytes per element)

§

F32

32-bit IEEE 754 float (4 bytes per element)

§

I64

64-bit signed integer (8 bytes per element)

§

I32

32-bit signed integer (4 bytes per element)

§

U8

8-bit unsigned integer (1 byte per element)

§

Bool

Boolean (1 byte per element; 0x00 = false, 0x01 = true) Note: NOT packed bits — 1 byte per bool for simplicity and alignment. Packed-bit BoolTensor can be a future optimization.

§

Bf16

Brain float 16-bit (2 bytes per element)

§

F16

IEEE 754 half-precision float (2 bytes per element)

§

Complex

Complex f64 pair (16 bytes per element: 8 re + 8 im)
