lib.rs

1//! The library that underlies most things [lockbook](https://lockbook.net).
2//!
3//! All lockbook clients
4//! (iOS, linux, etc) rely on this library to perform cryptography, offline edits, and
5//! reconciliation of data between our server, other clients, and other devices.
6//!
7//! Our server relies on this library for checking signatures, and validating whether tree
8//! modifications are valid / authorized.
9//!
10//! - Most clients / integrators will be interested in the functions attached to the [Lb] struct.
11//!   See the [service] module for evolving this functionality.
12//! - The [model] module contains the specification of our data structures and contracts between
13//!   components.
14//! - The [blocking] module contains blocking variants of all [Lb] functions for consumers without
15//!   async runtimes.
16//! - The [io] module contains interactions with disk and network.
