PROTOCOLS

Connector

Defined in fuchsia.power.clientlevel/clientlevel.fidl

Allows a client to connect a Watcher to the power level of a given ClientType.

Connect

Connects a Watcher to the power level of the specified ClientType.

A client may call this method and begin using the Watcher client endpoint immediately.

If a power configuration does not exist for the provided client_type, then the request will fail. On failure, both the watcher server endpoint as well as the current Connector connection will be terminated.

  • client_type specifies to which ClientType power level that watcher should be connected. The value is valid iff a power configuration exists for the provided client_type.

  • watcher is the server endpoint of a Watcher channel that will be connected to the ClientType power level.

Watcher

Defined in fuchsia.power.clientlevel/clientlevel.fidl

Allows a client to watch for changes to the power level of a given ClientType.

This protocol cannot be connected to the service directly. Instead, the server endpoint of a Watcher channel must first be connected to the power level of the desired ClientType using the Connector.Connect method. The client endpoint of a Watcher channel is only useful after it has been connected in this way.

Watch

Watches for changes to the power level of the connected ClientType.

The power level for a given ClientType is determined according to the power configuration for that ClientType. See the README.md for more details.

On a given connection, the first call will return immediately with the current power level for the connected ClientType. Subsequent Watch requests will only return a new level if the power level of the connected ClientType has changed. This follows the hanging get pattern.

  • level is an unsigned integer representing the power level of the connected ClientType.

ENUMS

ClientType flexible

Type: uint32

Defined in fuchsia.power.clientlevel/clientlevel.fidl

A value that represents the type of client using the protocol.

ClientType is used as a parameter for:

  1. Connector.Connect to connect a Watcher to the power level of the specified client type
  2. fuchsia.power.systemmode/ClientConfigurator.Get and fuchsia.power.systemmode/ClientConfigurator.Set to update the power configuration of the specified client type
