Function solana_ledger::blockstore::commit_slot_meta_working_set

fn commit_slot_meta_working_set(
    slot_meta_working_set: &HashMap<u64, SlotMetaWorkingSetEntry>,
    completed_slots_senders: &[Sender<Vec<u64>>],
    write_batch: &mut WriteBatch<'_>
) -> Result<(bool, Vec<u64>)>

For each slot in the slot_meta_working_set which has any change, include corresponding updates to cf::SlotMeta via the specified write_batch. The write_batch will later be atomically committed to the blockstore.

Arguments:

• slot_meta_working_set: a map that maintains slot-id to its SlotMeta mapping.
• completed_slot_senders: the units which are responsible for sending signals for completed slots.
• write_batch: the write batch which includes all the updates of the the current write and ensures their atomicity.

On success, the function returns an Ok result with <should_signal, newly_completed_slots> pair where:

• should_signal: a boolean flag indicating whether to send signal.
• newly_completed_slots: a subset of slot_meta_working_set which are newly completed.
