Source §

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

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

Source §

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