Struct MapperSessionProxy 

pub struct MapperSessionProxy { /* private fields */ }

Implementations

impl MapperSessionProxy

pub fn new(channel: Channel) -> Self

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

pub fn take_event_stream(&self) -> MapperSessionEventStream

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, FDomainResourceDialect>

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 create_vmo( &self, key: u64, size: u64, options: CreateVmoOptions, ) -> QueryResponseFut<MapperSessionCreateVmoResult, FDomainResourceDialect>

Creates a pager-backed VMO of size bytes associated with key. Page faults on this VMO are handled directly by the driver mapper.

pub fn open_child_session( &self, session: ServerEnd<MapperSessionMarker>, mapping_vmo: Vmo, parent_key: u64, port: Option<Port>, delivery_queue: Option<Vmo>, ) -> QueryResponseFut<MapperSessionOpenChildSessionResult, FDomainResourceDialect>

Opens a child mapper session whose reads map through parent_key in the parent session. When a parent session is closed, all child sessions opened from it are closed as well.

Trait Implementations

impl Clone for MapperSessionProxy

fn clone(&self) -> MapperSessionProxy

impl MapperSessionProxyInterface for MapperSessionProxy

type CloseResponseFut = QueryResponseFut<Result<(), i32>, FDomainResourceDialect>

type CreateVmoResponseFut = QueryResponseFut<Result<Vmo, i32>, FDomainResourceDialect>

type OpenChildSessionResponseFut = QueryResponseFut<Result<(), i32>, FDomainResourceDialect>

fn close(&self) -> Self::CloseResponseFut

fn create_vmo( &self, key: u64, size: u64, options: CreateVmoOptions, ) -> Self::CreateVmoResponseFut

fn open_child_session( &self, session: ServerEnd<MapperSessionMarker>, mapping_vmo: Vmo, parent_key: u64, port: Option<Port>, delivery_queue: Option<Vmo>, ) -> Self::OpenChildSessionResponseFut

impl Proxy for MapperSessionProxy

type Protocol = MapperSessionMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.

fn into_channel(self) -> Result<Channel, Self>

Attempt to convert the proxy back into a channel.

fn as_channel(&self) -> &Channel

Get a reference to the proxy’s underlying channel.

fn into_client_end(self) -> Result<ClientEnd<Self::Protocol>, Self>

Attempt to convert the proxy back into a client end.

fn domain(&self) -> Arc<Client>

Get the client supporting this proxy. We call this a “domain” here because:

fn on_closed(&self) -> OnFDomainSignals

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