//! # peach-web
//!
//! `peach-web` provides a web interface for monitoring and interacting with the
//! PeachCloud device. This allows administration of the single-board computer
//! (ie. Raspberry Pi) running PeachCloud, as well as the ssb-server and related
//! plugins.
//!
//! ## Design
//!
//! `peach-web` is written primarily in Rust and presents a web interface for
//! interacting with the device. The stack currently consists of Rocket (Rust
//! web framework), Tera (Rust template engine inspired by Jinja2 and the Django
//! template language), HTML, CSS and JavaScript. Additional functionality is
//! provided by JSON-RPC clients for the `peach-network` and `peach-stats`
//! microservices.
//!
//! HTML is rendered server-side. Request handlers call JSON-RPC microservices
//! and serve HTML and assets. A JSON API is exposed for remote calls and
//! dynamic client-side content updates via vanilla JavaScript following
//! unobstructive design principles. Each Tera template is passed a context
//! object. In the case of Rust, this object is a `struct` and must implement
//! `Serialize`. The fields of the context object are available in the context
//! of the template to be rendered.
