Problem
The block explorer needs to know the last entry_id of a valid block, ie. the block id, in order to display and organize by this identifier. It is currently very difficult for the service to determine the appropriate entry.
Summary of Changes
Adds Output struct and traits to EntryStream to get rid of duplication (and potential for bugs) between mock and live streams.
Adds
emit_block_event
method to EntryStreamImplements logic (based on current ReplayStage code) in EntryStreamStage to stream block events; this will need to be updated when forking-bank code lands.
Closes #2666 (refactor)
