Functions
`` |  | TimelineName(name, source_type, value_type) `Constructs the standard name given in the timeline. Args: name: The name of the timeline, for example "total", or "render_compositor". source_type: One of "cpu", "gpu" or None. None is only used for total times. value_type: the type of value. For example "mean", "stddev"...etc.`
