Constants ¶
const ( // AccountKVNamespace is the bucket name for account AccountKVNamespace = "Account" // ArchiveNamespacePrefix is the prefix of the buckets storing history data ArchiveNamespacePrefix = "Archive" // CurrentHeightKey indicates the key of current factory height in underlying DB CurrentHeightKey = "currentHeight" // ArchiveTrieNamespace is the bucket for the latest state view ArchiveTrieNamespace = "AccountTrie" // ArchiveTrieRootKey indicates the key of accountTrie root hash in underlying DB ArchiveTrieRootKey = "archiveTrieRoot" )
Variables ¶
var ( // ErrNotSupported is the error that the statedb is not for archive mode ErrNotSupported = errors.New("not supported") // ErrNoArchiveData is the error that the node have no archive data ErrNoArchiveData = errors.New("no archive data") //DefaultConfig is the default config for state factory DefaultConfig = Config{ Chain: blockchain.DefaultConfig, Genesis: genesis.Default, } )
