//! This module is used by crates which need to implement a "sync engine".
//! At a high-level, a "sync engine" is code which knows how to take records
//! from a sync server, apply and reconcile them with the local data, then
//! provide records which should be uploaded to the server.
//!
//! Note that the "sync engine" does not itself talk to the server, nor does
//! it manage the state of the remote server, nor does it do any of the
//! encryption/decryption - that is the responsbility of the "sync client", as
//! implemented in the [client] module (or in some cases, implemented externally)
//!
//! There are currently 2 types of engine:
//! * Code which implements the [crate::engine::sync_engine::SyncEngine]
//! trait. These are the "original" Rust engines, designed to be used with
//! the [crate::client](sync client)
//! * Code which implements the [crate::engine::bridged_engine::BridgedEngine]
//! trait. These engines are a "bridge" between the Desktop JS Sync world and
//! this rust code.
//! While these engines end up doing the same thing, the difference is due to
//! implementation differences between the Desktop Sync client and the Rust
//! client.
//! We intend merging these engines - the first step will be to merge the
//! types and payload management used by these traits, then to combine the
//! requirements into a single trait that captures both use-cases.
