pub struct StoreProxy { /* private fields */ }

Implementations

impl StoreProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for examples.keyvaluestore.supportexports/Store.

pub fn take_event_stream(&self) -> StoreEventStream

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

Panics

Panics if the event stream was already taken.

pub fn write_item( &self, attempt: &Item ) -> QueryResponseFut<StoreWriteItemResult>

Writes an item to the store.

pub fn export(&self, empty: Vmo) -> QueryResponseFut<StoreExportResult>

Exports the entire store as a persistent Exportable FIDL object into a VMO provided by the client.

By having the client provide (and speculatively size) the VMO, we force the party requesting the relatively heavy load of generating a backup to acknowledge and bear some of the costs.

This method operates by having the client supply an empty VMO, which the server then attempts to fill. Notice that the server removes the zx.Rights.WRITE and zx.Rights.SET_PROPERTY rights from the returned VMO - not even the requesting client may alter the backup once it has been minted by the server.
