class ReachabilityWatcher
Defined at line 25 of file ../../src/connectivity/network/lib/net_interfaces/cpp/reachability.h
Reads events from |watcher| and calls |callback| with a boolean network-reachability value iff it
has changed since the previously-reported value (the first value reported will be based on the
first interface existing or added event).
Upon encountering a non-recoverable error, e.g. the watcher FIDL
channel closing or receiving an invalid event from the server, |callback| will be called with
the error, and will never be called again.
