SplittableBuffer

storage_device::splittable_buffer

Struct SplittableBuffer

pub struct SplittableBuffer { /* private fields */ }

Expand description

A wrapper around OwnedBuffer that allows carving out independent child OwnedBuffers and recovering the original OwnedBuffer via a SplittableBufferHandle once all child buffers have been dropped.

Implementations§

impl SplittableBuffer

pub fn new(buffer: OwnedBuffer) -> (Self, SplittableBufferHandle)

Creates a new SplittableBuffer along with a clonable SplittableBufferHandle that can be used to recover the merged buffer once all child OwnedBuffers and other handles drop.

pub fn remaining_range(&self) -> Range<usize>

Returns the remaining unallocated range available for splitting.

pub fn take_prefix(&mut self, len: usize) -> OwnedBuffer

Carves out the first len bytes of the remaining unsplit buffer as a new OwnedBuffer.

§Panics

Panics if len exceeds remaining_range.len().
