Struct ZeroCopyBuffer 

pub struct ZeroCopyBuffer { /* private fields */ }

Zero-copy buffer that manages memory without copying

Implementations

impl ZeroCopyBuffer

pub fn new( size: usize, numanode: Option<usize>, alignment: usize, ) -> CoreResult<Self>

Create a new zero-copy buffer

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

Get a slice view of the buffer

Safety

This is safe because:

• The buffer lifetime is managed by reference counting
• The pointer is guaranteed to be valid while the buffer exists
• The size is validated during allocation and stored immutably
• The memory is properly aligned and initialized (zeroed)

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

Get a mutable slice view of the buffer

Safety

This is safe because:

• Exclusive access is guaranteed by &mut self
• The pointer is guaranteed to be valid while the buffer exists
• The size is validated during allocation and stored immutably
• The memory is properly aligned and initialized

pub fn share(&self) -> CoreResult<Self>

Create a shared reference to this buffer

Errors

Returns CoreError::MemoryError if the reference count would overflow

pub fn size(&self) -> usize

Get the size of the buffer

pub fn numa_node(&self) -> Option<usize>

Get the NUMA node ID

pub fn is_unique(&self) -> bool

Check if this is the only reference to the buffer

pub fn ref_count(&self) -> usize

Get the reference count
