Structs

AccountMeta

This struct will be backed by mmaped and snapshotted data files. So the data layout must be stable and consistent across the entire cluster!

AppendVec

A thread-safe, file-backed block of memory used to store Account instances. Append operations are serialized such that only one thread updates the internal append_lock at a time. No restrictions are placed on reading. That is, one may read items from one thread while another is appending new items.

AppendVecAccountsIter

StoredAccountMeta

References to account data stored elsewhere. Getting an Account requires cloning (see StoredAccountMeta::clone_account()).

StoredMeta

Meta contains enough context to recover the index from storage itself This struct will be backed by mmaped and snapshotted data files. So the data layout must be stable and consistent across the entire cluster!
