Trait polkadot_sdk_frame::traits::EnqueueMessage

pub trait EnqueueMessage<Origin>
where
    Origin: MaxEncodedLen,
{
    type MaxMessageLen: Get<u32>;

    // Required methods
    fn enqueue_message(
        message: BoundedSlice<'_, u8, Self::MaxMessageLen>,
        origin: Origin,
    );
    fn enqueue_messages<'a>(
        messages: impl Iterator<Item = BoundedSlice<'a, u8, Self::MaxMessageLen>>,
        origin: Origin,
    );
    fn sweep_queue(origin: Origin);
    fn footprint(origin: Origin) -> QueueFootprint;
}

Can enqueue messages for multiple origins.

Required Associated Types

type MaxMessageLen: Get<u32>

The maximal length any enqueued message may have.

Required Methods

fn enqueue_message( message: BoundedSlice<'_, u8, Self::MaxMessageLen>, origin: Origin, )

Enqueue a single message from a specific origin.

fn enqueue_messages<'a>( messages: impl Iterator<Item = BoundedSlice<'a, u8, Self::MaxMessageLen>>, origin: Origin, )

Enqueue multiple messages from a specific origin.

fn sweep_queue(origin: Origin)

Any remaining unprocessed messages should happen only lazily, not proactively.

fn footprint(origin: Origin) -> QueueFootprint

Return the state footprint of the given queue.
