This function is called on injection of a block by a particular baker. It allows us to inspect, change, or discard the block. Calling the injection RPC and actually updating the state of the mockup node are two different operations. Normally the first entails the latter, but not always. In particular, the propagation_vector controls what bakers will see and incorporate the block.

This function is called on injection of an operation. It is similar to on_inject_block, which see.

This is called when a new validated block is going to be sent as the response to a "monitor validated blocks" RPC call. Returning None here terminates the process for the baker.

This is called when a new head is going to be sent as the response to a "monitor heads" RPC call. Returning None here terminates the process for the baker.

This is called when a new operation is going to be sent as the response to a "monitor operations" RPC call. Returning None here indicates that the node has advanced to the next level.

Check a block before processing it in the mockup.

Check the chain after processing a proposal.

Check operations in the mempool after injecting an operation.

This hook is used to decide when the baker is supposed to shut down. It is triggered by receiving an event.

This hook is used to gather information on the baker when it is started (usually recording for later use). The first argument baker_position, is the position of the baker in the list of bakers that were started for this run.

Check to run on the chain upon successful termination.
