    // Required method
    fn service_queues(weight_limit: Weight) -> Weight;

    // Provided method
    fn execute_overweight(

        _address: Self::OverweightMessageAddress,
    ) -> Result<Weight, ExecuteOverweightError> { ... }
}

Can service queues and execute overweight messages.

Required Associated Types

type OverweightMessageAddress

Addresses a specific overweight message.

Required Methods

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.

Provided Methods

fn execute_overweight( _weight_limit: Weight, _address: Self::OverweightMessageAddress, ) -> Result<Weight, ExecuteOverweightError>

Executes a message that could not be executed by Self::service_queues() because it was temporarily overweight.

Object Safety

This trait is not object safe.
