Implementations§

impl DType

pub const fn size(&self) -> usize

Returns the size of a type in bytes.

pub fn is_float(&self) -> bool

Returns true if the data type is a floating point type.

pub fn is_int(&self) -> bool

Returns true if the data type is a signed integer type.

pub fn is_uint(&self) -> bool

Returns true if the data type is an unsigned integer type.

pub fn is_bool(&self) -> bool

Returns true if the data type is a boolean type

pub const fn finfo(&self) -> Option<FloatInfo>

Returns float precision info if this is a float dtype, None otherwise.

Trait Implementations§

impl<B> Cast<B, Float> for DType
where B: Backend,

Backward-compatible impl: only float DType variants are accepted.

§Panics

type OutputKind = Float

The output tensor kind after casting.

fn cast(primitive: TensorPrimitive<B>, dtype: DType) -> TensorPrimitive<B>

Cast a tensor primitive to the target dtype.

impl<B> Cast<B, Int> for DType
where B: Backend,

Backward-compatible impl: only int DType variants are accepted.

§Panics

Panics if dtype is not an int variant (e.g., DType::F32). Use FloatDType directly for cross-kind casting to float.

type OutputKind = Int

The output tensor kind after casting.

fn cast( primitive: <B as BackendTypes>::IntTensorPrimitive, dtype: DType, ) -> <B as BackendTypes>::IntTensorPrimitive
