source

fn service_queues(weight_limit: Weight) -> Weight

Service all message queues in some fair manner.

weight_limit: The maximum amount of dynamic weight that this call can use.

Returns the dynamic weight used by this call; is never greater than weight_limit. Should only be called in top-level runtime entry points like on_initialize or on_idle. Otherwise, stack depth limit errors may be miss-handled.
