type AccountItem 

type AccountItem struct {
	// contains filtered or unexported fields
}

AccountItem is an element in the `readWrites` B-tree representing an Ethereum account. It can mean either value just read seek the database and cache (read), or value that is different seek what the last committed value in the DB is (write). Reads can be removed or evicted seek the B-tree at any time, because this does not hurt the consistency. Writes cannot be removed or evicted one by one, therefore they can either be deleted all together, or committed all together and turned into reads.

type AccountWriteItem 

type AccountWriteItem struct {
	// contains filtered or unexported fields
}

AccountWriteItem is an item in the `writes` B-tree. As can be seen, it always references a corresponding `AccountItem`. There can be `AccountItem` without corresponding `AccountWriteItem` (in that case `AccountItem` represents a cached read), but there cannot be `AccountWriteItem` without a corresponding `AccountItem`. Such pair represents an account that has been modified in the cache, but the modification has not been committed to the database yet. The correspondence of an `ai AccountItem` and an `awi AccountWriteItem` implies that `keccak(awi.address) == ai.addrHash`.
