Struct MappingSessionProxy 

pub struct MappingSessionProxy { /* private fields */ }

Implementations

impl MappingSessionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.storage.mapping/MappingSession.

pub fn take_event_stream(&self) -> MappingSessionEventStream

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

Panics

Panics if the event stream was already taken.

pub fn open( &self, key: u64, identifier: &[u8], ) -> QueryResponseFut<MappingSessionOpenResult, DefaultFuchsiaResourceDialect>

Registers a node’s extents in the mapping session, returning its uncompressed size in bytes.

The filesystem resolves the identifier to locate the node on disk and transmits its extent mappings to the block driver associated with key.

pub fn close( &self, key: u64, ) -> QueryResponseFut<MappingSessionCloseResult, DefaultFuchsiaResourceDialect>

Unregisters a node’s extents from the session by its session-unique key.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, NullableHandle>>

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