Enum CudaStorage 

pub enum CudaStorage {
    F16(CudaSlice<u16>),
    BF16(CudaSlice<u16>),
    F32(CudaSlice<f32>),
    F64(CudaSlice<f64>),
    U8(CudaSlice<u8>),
    U32(CudaSlice<u32>),
    I64(CudaSlice<i64>),
}

Re-export CUDA backend (requires cuda feature + NVIDIA CUDA Toolkit). GPU-side storage. Each variant wraps a cudarc CudaSlice for the corresponding dtype. F16 and BF16 are stored as CudaSlice (bit-level representation).

Variants

F16(CudaSlice<u16>)

BF16(CudaSlice<u16>)

F32(CudaSlice<f32>)

F64(CudaSlice<f64>)

U8(CudaSlice<u8>)

U32(CudaSlice<u32>)

I64(CudaSlice<i64>)

Implementations

impl CudaStorage

pub fn as_cuda_slice_f32(&self) -> Result<&CudaSlice<f32>, Error>

Get the underlying CudaSlice (returns error if dtype doesn’t match).

pub fn as_cuda_slice_u16(&self) -> Result<&CudaSlice<u16>, Error>

Get the underlying CudaSlice for F16 or BF16 storage.

pub fn from_f32_vec( data: Vec<f32>, device: &CudaDevice, ) -> Result<CudaStorage, Error>

Transfer data from host Vec to a new CudaStorage on the given device.

pub fn from_f64_vec( data: Vec<f64>, device: &CudaDevice, ) -> Result<CudaStorage, Error>

Transfer data from host Vec to a new CudaStorage on the given device.

pub fn from_f16_vec( data: Vec<f16>, device: &CudaDevice, ) -> Result<CudaStorage, Error>

Transfer data from host Vec to a new F16 CudaStorage on the given device.

pub fn from_bf16_vec( data: Vec<bf16>, device: &CudaDevice, ) -> Result<CudaStorage, Error>

Transfer data from host Vec to a new BF16 CudaStorage on the given device.

pub fn to_host_f64(&self, device: &CudaDevice) -> Result<Vec<f64>, Error>

Copy all data to host as Vec.
