Struct ErasedRawStridedRef 

pub struct ErasedRawStridedRef<'a> { /* private fields */ }

Borrowed dtype-erased raw strided input layout.

dims, strides, and offset are expressed in dtype elements, not bytes.

Implementations

impl<'a> ErasedRawStridedRef<'a>

pub fn from_slice<T>( data: &'a [T], dims: &'a [usize], strides: &'a [isize], offset: isize, ) -> Result<ErasedRawStridedRef<'a>, StridedError>

where T: KernelStorageElement,

Create an erased input descriptor from typed, initialized storage.

pub unsafe fn from_raw_parts( dtype: KernelDType, data: NonNull<u8>, byte_len: usize, dims: &'a [usize], strides: &'a [isize], offset: isize, ) -> Result<ErasedRawStridedRef<'a>, StridedError>

Construct from erased storage.

Safety

data must be the start of an allocation aligned for dtype; the allocation must contain byte_len initialized, readable bytes for 'a, and every byte extent must represent valid values for dtype. The allocation and metadata must outlive 'a; no mutable alias may exist while this descriptor is used. Alignment is an allocation property and must not be inferred from the observed address alone.

pub fn data_as<T>(&self) -> Result<&[T], StridedError>

where T: KernelStorageElement,

Borrow the initialized storage as its concrete scalar type.

pub fn dtype(&self) -> KernelDType

pub fn dims(&self) -> &'a [usize]

pub fn strides(&self) -> &'a [isize]
