Struct WatcherV4Proxy

pub struct WatcherV4Proxy { /* private fields */ }

Implementations

impl WatcherV4Proxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.net.routes/WatcherV4.

pub fn take_event_stream(&self) -> WatcherV4EventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch( &self, ) -> QueryResponseFut<Vec<EventV4>, DefaultFuchsiaResourceDialect>

Hanging-Get style API for observing routing changes.

Clients must only have one pending Watch call at a time. Calling Watch while a request is already pending will cause the protocol to close.

The first N events will always be existing where N is the number of IPv4 routes that already existed when the server-end of the protocol was initialized. The following event will be idle signaling the end of the existing events. At this point the client has watched all existing state and will never again observe an existing event.

Events are returned in batches of up to MAX_EVENTS events. There is no correlation between the batch size/boundary and it’s contents: it is perfectly valid for the server to split the block of existing events, across several batches. Clients should view this API as providing a stream of events, where batches are used to reduce IPC load on the system.

• response events A vector of at most MAX_EVENTS events.
