Struct DefaultCallbackBlockService 

pub struct DefaultCallbackBlockService<I: Interface + ?Sized> { /* private fields */ }

Default fallback implementation of BlockService for [callback_interface::Interface] backends (such as C++ drivers / virtio-block) that return the default implementation from into_block_service.

Trait Implementations

impl<I: Interface + ?Sized> BlockService for DefaultCallbackBlockService<I>

fn allocate_buffer(&self, max_len: usize) -> OwnedBuffer

Allocates a read buffer of at most max_len bytes (OwnedBuffer).

fn read_blocks( &self, device_offset: u64, dest_buffer: OwnedBuffer, on_complete: Box<dyn FnOnce(Result<OwnedBuffer, Error>) + Send>, ) -> Result<(), Error>

Submits a read for the specified range from device_offset into dest_buffer. When the read completes, on_complete is invoked with the result containing the buffer.
