void ~Input ()

void Watch (WatchCallback callback)

Gets the current |InputSettings|. Returns immediately on first call;

subsequent calls return when the value changes.

When any of the input devices' states change, this will return the

full [InputSettings] object, containing the states for all the

available input devices on the target device.

To find the state of a specific input device, the devices vector

contained in settings can be iterated through to find a specific

[DeviceType]. If there are multiple devices of the same [DeviceType],

the [InputDevice]'s device_name can be examined in conjunction with

the [DeviceType] to find the desired input device. Together, the

device_name and [DeviceType] uniquely identify an [InputDevice].

If this call fails, it is considered a fatal error and the channel

will be closed.

void Set (::std::vector< ::fuchsia::settings::InputState> input_states, SetCallback callback)

Requests software input devices to set their software state. May

not necessarily change the overall state of the device, depending on

the hardware state. Will modify the software state of the existing

device if a known device_name and device_type are passed. Otherwise

it will add a new input device. Devices not included in input_states

will not be modified.
