fn flush<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), Status>> + Send + 'async_trait>>

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

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

Closes the fifo.

fn block_size(&self) -> u32

Returns the block size of the device.

fn block_count(&self) -> u64

Returns the size, in blocks, of the device.

fn block_flags(&self) -> Flag

Returns the block flags reported by the device.

fn is_connected(&self) -> bool

Returns true if the remote fifo is still connected.

fn write_at<'life0, 'life1, 'async_trait>( &'life0 self, buffer_slice: BufferSlice<'life1>, device_offset: u64, ) -> Pin<Box<dyn Future<Output = Result<(), Status>> + Send + 'async_trait>>
