Fields§

§last_local_block: u64

The last local (starknet) block for which messages have been collected and sent.

§l2_to_l1_messages_hashes: HashMap<String, u64>

A local queue of MessageToL1 hashes generated by cairo contracts. For each time a message is supposed to be sent to L1, it is stored in this queue. The user may consume those messages using consume_message_from_l2 to actually test MessageToL1 emitted without running L1 node.

Note: Hash256 is not directly supported as a HashMap key due to missing trait. Using String instead.

§l2_to_l1_messages_to_flush: Vec<MessageToL1>

This list of messages that will be sent to L1 node at the next postman/flush.
