pub unsafe fn id(&self) -> u32

Source

pub unsafe fn data(&self) -> *mut u8

Source

pub unsafe fn slice(&self, range: Range<usize>) -> &[u8]

Source

pub unsafe fn slice_mut(&self, range: Range<usize>) -> &mut [u8]

Source

pub unsafe fn set_next(&self, next: Option<BufferPtr>)

SAFETY: this method must not be called concurrently from multiple threads.

Source

pub unsafe fn swap_next(&self, new_next: Option<BufferPtr>) -> Option<BufferPtr>

SAFETY: this method must not be called concurrently from multiple threads.

Source

pub unsafe fn get_next(&self) -> Option<BufferPtr>

SAFETY: this method must not be called concurrently with set_next or swap_next from multiple threads.

Source

pub unsafe fn writer_id(&self) -> usize

SAFETY: you must have exclusive access to this buffer.

Source

pub unsafe fn set_writer_id(&self, writer_id: usize)

SAFETY: you must have exclusive access to this buffer.

Source

pub unsafe fn release(self)

Release this buffer back to the pool it was acquired from.

SAFETY: you must have exclusive access to this buffer.

Source

pub unsafe fn initialize_rc(&self, count: u32, local_shared: u32, shared: u32)

You must ensure that you have exclusive access to the reference count of the buffer - that no other threads try to take or release references to this buffer between this buffer being acquired from the pool and the call to this method.

Source

pub unsafe fn send(&self) -> u32

Used when converting a LocalPacket into a sendable Packet. Increments the shared reference count and decrements the thread-local reference count.

Returns the shared_rc_contribution value that the receiving thread should add to its own.

Source

pub unsafe fn send_bulk(&self, count: u32) -> u32

Used when converting a LocalPacket into a sendable Packet. Increments the shared reference count and decrements the thread-local reference count.

Returns the shared_rc_contribution value that the receiving thread should add to its own.

Source

pub unsafe fn receive(&self, shared_rc_contribution: u32)

Used when converting a LocalPacket into a sendable Packet. Increments the shared reference count and decrements the thread-local reference count.

Source

pub unsafe fn take_ref(&self, count: u32) -> u32

Source

pub unsafe fn take_shared_ref(&self, count: u32)

Source

pub unsafe fn release_ref(&self, count: u32)
