Enum fidl_fuchsia_hardware_block::SessionRequest

pub enum SessionRequest {
    Close {
        responder: SessionCloseResponder,
    },
    GetFifo {
        responder: SessionGetFifoResponder,
    },

    },
}

Represents a session with a block device.

This protocol encodes the underlying object’s lifetime in both directions; the underlying object is alive iff both ends of the protocol are open. That is:

• Closing the client end causes the object to be destroyed.
• Observing a closure of the server end indicates the object no longer exists.

The object can be destroyed synchronously using [fuchsia.unknown/Closeable.Close].

Variants

Close

Terminates the connection.

After calling Close, the client must not send any other requests.

Servers, after sending the status response, should close the connection regardless of status and without sending an epitaph.

Closing the client end of the channel should be semantically equivalent to calling Close without knowing when the close has completed or its status.

Fields

responder: SessionCloseResponder

GetFifo

Returns a handle to the client end of the FIFO.

Fields

responder: SessionGetFifoResponder

AttachVmo

Attaches a VMO to the session.

Returns an identifer that can be used to refer to the VMO.

Fields

vmo: Vmo

responder: SessionAttachVmoResponder
