pub(crate) type BalIndexSetter<DB> = fn(&mut DB, u64);Expand description
Function pointer that overwrites the BAL index in the DB.
Used in BbBlockExecutor::initialize to map a worker’s incoming
bal_index = i + 1 (the standard “tx i + 1” convention from
execute_block_in_pool) onto the renumbered space i + 1 + 2k, where
k is the segment index containing tx i. Renumbering reserves two
extra bal_indexes per segment boundary (one for each segment’s
post-execution and one for the next segment’s pre-execution), so workers’
strict less-than reads can see those boundary writes.
