Struct C64 

#[repr(transparent)]
pub struct C64(pub [f64; 2]);

128-bit interleaved complex ({re, im} of f64). Layout matches cufft_sys::double2 and numpy.complex128. Phase 1.5++.

Maps to cudaDataType_t::CUDA_C_64F and cuDoubleComplex.

Tuple Fields

0: [f64; 2]

Implementations

impl C64

pub const fn new(re: f64, im: f64) -> Self

Construct from real / imaginary components.

pub fn re(self) -> f64

pub fn im(self) -> f64

Trait Implementations

impl AccelDtype for C64

const KIND: DType = DType::F64

Runtime discriminant.

const SIZE: usize = 16

Bytes per element including representation padding.

const NAME: &'static str = "complex128"

Human-readable name used in tracing and error messages.

type Scalar = f64

Companion scalar type for host-side parameters (alpha/beta, mean/std, scaling factors). Self for full-precision dtypes; f32 for fp8 / fp4 wrappers because the upstream APIs accept f32 scales.

fn zero() -> Self

fn one() -> Self

fn nan() -> Option<Self>

Some(NaN) for floats, None for integers.

impl Clone for C64

fn clone(&self) -> C64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CudaDtype for C64

fn cuda_data_type() -> cudaDataType_t

fn cublas_compute_type() -> cublasComputeType_t

fn cuda_type_name() -> &'static str

CUDA C++ type name for NVRTC source generation.

fn cudnn_data_type() -> cudnnDataType_t

fn nccl_data_type() -> ncclDataType_t

impl Debug for C64

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

Formats the value using the given formatter.

impl Default for C64

fn default() -> C64

Returns the “default value” for a type.

impl From<C64> for double2

Available on crate feature cufft only.

fn from(v: C64) -> Self

Converts to this type from the input type.

impl From<double2> for C64

Available on crate feature cufft only.

fn from(v: double2) -> Self

Converts to this type from the input type.

impl PartialEq for C64

fn eq(&self, other: &C64) -> 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 C64

impl DeviceRepr for C64

impl FftSupported for C64

impl StructuralPartialEq for C64

impl ValidAsZeroBits for C64
