Struct SplittableBuffer 

pub struct SplittableBuffer { /* private fields */ }

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: BufferImpl<'static, Arc<dyn BufferAllocator>, dyn BufferAllocator>, ) -> (SplittableBuffer, 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, ) -> BufferImpl<'static, Arc<dyn BufferAllocator>, dyn BufferAllocator>

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

Panics

Panics if len exceeds remaining_range.len().
