Struct AlignedBuffer 

pub struct AlignedBuffer { /* private fields */ }

Implementations

impl AlignedBuffer

pub fn new(capacity: usize) -> Result<Self>

Create a new aligned buffer with the given capacity.

Errors

Returns an error if memory allocation fails.

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

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

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

pub fn as_mut_slice(&mut self) -> &mut [u8]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub fn set_len(&mut self, len: usize)

pub fn write(&mut self, offset: usize, data: &[u8]) -> Result<()>

Write data at the specified offset.

Errors

Returns an error if write exceeds buffer capacity.

pub fn clear(&mut self)

pub fn mlock(&self) -> Result<()>

Lock the buffer in memory using mlock to prevent page faults. This ensures the buffer pages are resident in RAM and won’t be swapped.

Errors

Returns an error if mlock fails (e.g., insufficient privileges or limits).

pub fn prefault(&mut self)

Prefault all pages in the buffer by touching each page. This ensures pages are allocated and mapped before use on the hot path.

pub fn lock_and_prefault(&mut self) -> Result<()>

Lock and prefault the buffer for zero-latency access on hot path.

Errors

Returns an error if mlock fails.
