Enum DType 

#[non_exhaustive]
#[repr(u32)]
pub enum DType {
    U8 = 0,
    I8 = 1,
    U16 = 2,
    I16 = 3,
    U32 = 4,
    I32 = 5,
    U64 = 6,
    I64 = 7,
    F16 = 8,
    F32 = 9,
    F64 = 10,
}

Element type discriminant for runtime type identification.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

U8 = 0

I8 = 1

U16 = 2

I16 = 3

U32 = 4

I32 = 5

U64 = 6

I64 = 7

F16 = 8

F32 = 9

F64 = 10

Implementations

impl DType

pub const fn code(self) -> u32

The shared code for this variant. Identical on every surface.

const, deliberately: a downstream binding that cannot write Variant = OtherEnum::Variant.code() in a #[pyclass] discriminant position (PyO3 requires a literal there) can still pin that literal to this value with a const _: () = assert!(...) – a build-time check instead of a hand-synced comment. See PyTensorMemory/PyPixelFormat in crates/python-common/src/tensor.rs for the consumer.

pub fn from_code(code: u32) -> Option<Self>

Reject an unknown code rather than guessing at one.

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

The wire string form – stable, unlike Debug.

pub fn from_str_code(s: &str) -> Option<Self>

Reject an unknown string rather than guessing at one.

pub fn all() -> &'static [Self]

Every variant, for exhaustive cross-surface tests.

impl DType

pub const fn size(&self) -> usize

Size of one element in bytes.

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

Short type name (e.g., “u8”, “f32”, “f16”). Identical to DType::as_str; kept as its own method for existing callers.
