Expand description

Returns the Id of the currently running task, or None if called outside of a task.

This function is similar to task::id(), except that it returns None rather than panicking if called outside of a task context.

Note: This is an unstable API. The public API of this type may break in 1.x releases. See the documentation on unstable features for details.
