SplittableBufferHandle

storage_device::splittable_buffer

Struct SplittableBufferHandle

pub struct SplittableBufferHandle { /* private fields */ }

Expand description

A clonable handle referencing the underlying SplittableBufferInner.

Can be captured inside background sub-read callbacks and consumed via into_buffer(self) once all child OwnedBuffers and other handles drop to recover the merged OwnedBuffer.

Implementations§

impl SplittableBufferHandle

pub fn into_buffer(self) -> Option<OwnedBuffer>

Consumes this handle and attempts to unwrap the underlying Arc<SplittableBufferInner>.

Returns Some(parent_buffer) if this handle and all child OwnedBuffers carved from SplittableBuffer have been dropped (Arc::strong_count == 1). Otherwise returns None.
