Implementations

impl DType

pub const fn size(&self) -> usize

Available on crate feature api only.

Returns the size of a type in bytes.

pub fn is_float(&self) -> bool

Available on crate feature api only.

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

pub fn is_int(&self) -> bool

Available on crate feature api only.

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

pub fn is_uint(&self) -> bool

Available on crate feature api only.

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

pub fn is_bool(&self) -> bool

Available on crate feature api only.

Returns true if the data type is a boolean type

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

Available on crate feature api only.

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

Analogous to torch.finfo(dtype) or numpy.finfo(dtype).

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

Available on crate feature api only.

Returns the data type name.

Trait Implementations

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

Available on crate feature api only.

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

Panics

Panics if dtype is not a float variant (e.g., DType::I32). Use IntDType directly for cross-kind casting to int.

type OutputKind = Float

The output tensor kind after casting.

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

Cast a tensor primitive to the target dtype.

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

Available on crate feature api only.

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::IntTensorPrimitive, dtype: Self) -> B::IntTensorPrimitive

Cast a tensor primitive to the target dtype.

impl Clone for DType

fn clone(&self) -> DType

Returns a duplicate of the value.

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