Public Methods
::fidl::OneWayStatus AcknowledgeDeviceEvent ()AcknowledgeDeviceEvent must be called after any of the above events before more
events will be sent.
Caller provides the backing storage for FIDL message via an argument to `.buffer()`.
::fidl::WireUnownedResult< ::fuchsia_camera2::Manager::ConnectToStream> ConnectToStream (int32_t device_id, ::fuchsia_camera2::wire::StreamConstraints constraints, ::fidl::ClientEnd< ::fuchsia_sysmem::BufferCollectionToken> && token, ::fidl::ServerEnd< ::fuchsia_camera2::Stream> && stream)Connect to a camera stream:
`device_id` Refers to a specific device_id that has been advertised by OnDeviceAvailable.
`constraints` contains a set of constraints on the requested stream. The Camera
Manager will attempt to find a stream that meets the constraints. If multiple
streams match, one of the matching streams will be connected.
`token` refers to a Sysmem buffer allocation that will be used to pass images using
the Stream protocol. The Camera Manager will apply a BufferCollectionContraints
related to the image format(s), so the client does not need to apply any
ImageFormatConstraints.
Sync is assumed to have been called on `token` before it is passed to
ConnectToStream.
Since `constraints` may not dictate a specific format, the initial format of images
on the stream is indicated on the response.
The connection is considered to be successful once a response has been given, unless
`stream` is closed.
