Struct SliceWriter 

pub struct SliceWriter<'a, T> { /* private fields */ }

Utility for incrementally filling an uninitialized slice, one SIMD vector at a time.

Implementations

impl<'a, T: Elem> SliceWriter<'a, T>

pub fn new(buf: &'a mut [MaybeUninit<T>]) -> Self

Create a writer which initializes elements of buf.

pub fn write_vec<O: BitOps<T>>(&mut self, ops: O, xs: O::Simd)

Initialize the next ops.len() elements of the slice from the contents of SIMD vector xs.

Panics if the slice does not have space for ops.len() elements.

pub fn write_vecs<O: BitOps<T>, const N: usize>( &mut self, ops: O, xs: [O::Simd; N], )

Initialize the next N * ops.len() elements of the slice from the contents of the SIMD vectors xs.

This is equivalent to calling write_vec for each vector, but performs a single bounds check for the whole batch, which is useful when writing several vectors per loop iteration.

Panics if the slice does not have space for N * ops.len() elements.

pub fn write_scalar(&mut self, x: T)

Initialize the next element of the slice from x.

Panics if the slice does not have space for writing any more elements.

pub fn into_mut_slice(self) -> &'a mut [T]

Finish writing the slice and return the initialized portion.
