pub fn current_task() -> Option<TaskHandle>Expand description
This process’s own task, if it is itself running as one — read from
BASIS_TASK_ID. None for a value that is absent, blank, or does not
fit the task-handle grammar: basis’s own runtime always sets a well-formed
one, so a malformed value is not basis’s, and treating it as “no current
task” is the safer reading of somebody else’s environment variable.
