Struct SrcDest 

pub struct SrcDest<'src, 'dst, T: Copy> { /* private fields */ }

Input-output buffer for vectorized operations.

This can either be a single mutable buffer for operations that execute in-place (&mut [T]) or a pair of input and output buffers where the output is uninitialized (([T], &mut [MaybeUninit<T>])) and both buffers must have the same length.

Implementations

impl<'dst, T: Copy> SrcDest<'_, 'dst, T>

pub fn src(&self) -> &[T]

Return the source slice.

pub fn len(&self) -> usize

Return the length of the input and output slices.

pub fn is_empty(&self) -> bool

Return true if the input and output slices are empty.

pub fn src_dest_ptr(&mut self) -> (*const T, *mut MaybeUninit<T>, usize)

Return source and destination slice pointers and the length.

The source and destination will either alias, or the destination will be a non-aliasing, uninitialized slice.

pub unsafe fn dest_assume_init(self) -> &'dst mut [T]

Return the initialized destination slice.

Safety

If this instance was constructed with an uninitialized destination buffer, all elements must have been initialized before this is called.

Trait Implementations

impl<'dst, T: Copy> From<&'dst mut [T]> for SrcDest<'dst, 'dst, T>

fn from(val: &'dst mut [T]) -> Self

Converts to this type from the input type.

impl<'src, 'dst, T: Copy> From<(&'src [T], &'dst mut [MaybeUninit<T>])> for SrcDest<'src, 'dst, T>

fn from(val: (&'src [T], &'dst mut [MaybeUninit<T>])) -> Self

Converts to this type from the input type.
