pub fn assignment_state_stream(
address_state_provider: AddressStateProviderProxy,
) -> impl Stream<Item = Result<AddressAssignmentState, AddressStateProviderError>>Expand description
Returns a stream of assignment states obtained by watching on address_state_provider.
Note that this function calls the hanging get FIDL method
[AddressStateProviderProxy::watch_address_assignment_state] internally,
which means that this stream should not be polled concurrently with any
logic which calls the same hanging get. This also means that callers should
be careful not to drop the returned stream when it has been polled but yet
to yield an item, e.g. due to a timeout or if using select with another
stream, as doing so causes a pending hanging get to get lost, and may cause
future hanging get calls to fail or the channel to be closed.
