Struct AlignedPool 

pub struct AlignedPool { /* private fields */ }

A pre-allocated memory pool with 16-byte alignment guarantee.

Used by AlignedByteSlice to ensure that f32/f64 data mapped from raw bytes starts on a SIMD-friendly boundary. When source bytes are already aligned, no copy is needed; when misaligned, a one-time aligned copy is performed into the pool.

Implementations

impl AlignedPool

pub fn new(capacity_bytes: usize) -> Self

Create a new pool with capacity for at least capacity_bytes of 16-byte-aligned data. The actual allocation may be slightly larger.

pub fn as_ptr(&self) -> *const u8

Returns a pointer to the aligned region.

pub fn as_mut_ptr(&mut self) -> *mut u8

Returns a mutable pointer to the aligned region.

pub fn as_bytes(&self) -> &[u8]

Returns the aligned region as a byte slice.

pub fn is_aligned_16(ptr: *const u8) -> bool

Check if a raw pointer is 16-byte aligned.

pub fn copy_from(&mut self, data: &[u8]) -> Result<(), RuntimeError>

Copy data into the pool, returning the aligned byte slice. Returns an error if data exceeds pool capacity.

pub fn len(&self) -> usize

Current number of bytes stored.

pub fn is_empty(&self) -> bool

Whether the pool is empty.

pub fn capacity(&self) -> usize

Total capacity in bytes.

pub fn check_alignment(&self) -> bool

Verify that the aligned pointer is indeed 16-byte aligned.
