Public Methods
::fidl::WireUnownedResult< ::fuchsia_camera3::DeviceWatcher::WatchDevices> WatchDevices ()Returns a list of available camera IDs when it has changed from the previously returned
list of IDs, or when it is called by a client for the first time. The returned list may be
empty, indicating no cameras are available. The IDs returned to the client will remain
consistent with respect to the physical devices they represent for the duration of the
client's connection. Events will be sorted first by event type - `existing`, `added`,
`removed`. Within each event type range, IDs will be provided in ascending order. Events
are coalesced by the server, so a given ID will only appear once in each list of events.
Please note that it is entirely possible for the list returned to be temporarily empty even
if the local camera hardware is hardwired (vs plug-in like USB). The empty list condition
is temporary on such a platform.
Camera applications should tolerate an empty list returned, and attempt to retry the
`WatchDevices()` call.
Caller provides the backing storage for FIDL message via an argument to `.buffer()`.
::fidl::OneWayStatus ConnectToDevice (uint64_t id, ::fidl::ServerEnd< ::fuchsia_camera3::Device> && request)Acquires a camera interface for the given ID. If any clients already exist for this camera,
the request is closed with the ZX_ERR_ALREADY_BOUND epitaph.
