Struct AlignedBuffer 

pub struct AlignedBuffer { /* private fields */ }

A cache-line aligned buffer of f32 values.

Guarantees that the backing memory starts at a 64-byte boundary, which is optimal for AVX-512 aligned loads and cache line prefetch.

Example

use oxibonsai_kernels::aligned::AlignedBuffer;

let buf = AlignedBuffer::new(256);
assert_eq!(buf.len(), 256);
assert_eq!(buf.as_ptr() as usize % 64, 0);

Implementations

impl AlignedBuffer

pub fn new(len: usize) -> Self

Allocate a new zero-initialized aligned buffer of len f32 elements.

The returned buffer is guaranteed to have 64-byte alignment. A zero-length buffer produces a valid (dangling but aligned) pointer.

pub fn len(&self) -> usize

Returns the number of f32 elements in this buffer.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.

pub fn as_ptr(&self) -> *const f32

Returns the raw pointer to the start of the buffer.

pub fn as_mut_ptr(&mut self) -> *mut f32

Returns a mutable raw pointer to the start of the buffer.

pub fn as_slice(&self) -> &[f32]

View the buffer as an immutable slice.

pub fn as_mut_slice(&mut self) -> &mut [f32]

View the buffer as a mutable slice.

pub fn copy_from_slice(&mut self, src: &[f32])

Copy data from a slice into this buffer.

Panics if src.len() > self.len().

Trait Implementations

impl Debug for AlignedBuffer

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

Formats the value using the given formatter.

impl Drop for AlignedBuffer

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
