//! # Persisted State building blocks
//!
//! This crate provides a few types for working with databases. The types build upon those found in [holochain_sqlite::buffer].
//!
//! - [ElementBuf]: the union of two CasBuffers, one for Entries, one for Headers
//! - [ChainSequenceBuf]: database representing the chain sequence DB, which provides a special method for accessing the chain head
//! - [SourceChainBuf]: the union of a [ElementBuf] and a [ChainSequenceBuf], which fully represents a source chain
//! - [MetadataBuf]: (*unimplemented*) Uses a KvvBuffer to represent EAV-like relationships between CAS entries
//! - [Cascade]: (*unimplemented*) Unifies two [ElementBuf] and two [MetadataBuf] references (one of each is a cache) in order to perform the complex metadata-aware queries for getting entries and links, including CRUD resolution
//!
//! The follow diagram shows the composition hierarchy.
//! The arrows mean "contains at least one of".
