Required Methods

fn read<'life0, 'life1, 'async_trait>( &'life0 self, offset: u64, buf: MutableBufferRef<'life1>, ) -> Pin<Box<dyn Future<Output = Result<usize, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fills |buf| with up to |buf.len()| bytes read from |offset| on the underlying device. |offset| and |buf| must both be block-aligned.

fn get_size(&self) -> u64

Returns the size of the object.
