Struct SessionProxy 

pub struct SessionProxy { /* private fields */ }

Implementations

impl SessionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.storage.block/Session.

pub fn take_event_stream(&self) -> SessionEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn close( &self, ) -> QueryResponseFut<CloseableCloseResult, DefaultFuchsiaResourceDialect>

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.

pub fn get_fifo( &self, ) -> QueryResponseFut<SessionGetFifoResult, DefaultFuchsiaResourceDialect>

Returns a handle to the client end of the FIFO.

pub fn attach_vmo( &self, vmo: Vmo, ) -> QueryResponseFut<SessionAttachVmoResult, DefaultFuchsiaResourceDialect>

Attaches a VMO to the session. Resizable VMOs are not supported and will return ZX_ERR_INVALID_ARGS.

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

pub fn register_key( &self, key_token: EventPair, ) -> QueryResponseFut<SessionRegisterKeyResult, DefaultFuchsiaResourceDialect>

Registers an inline encryption key handle (key_token returned by fuchsia.hardware.inlineencryption/Device.ProgramKey) with this session.

Returns a session-scoped slot token that can be passed in BlockFifoRequest.slot when BlockIoFlag.INLINE_ENCRYPTION_ENABLED is set.

• error ZX_ERR_ACCESS_DENIED if key_token is not a valid inline encryption key token for this block device, or if the key has been evicted.
• error ZX_ERR_NOT_SUPPORTED if the device does not support inline encryption.

Trait Implementations

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
