//! This crate serves to provide metrics bindings to be used throughout the codebase.
//! For binaries that wish to use metrics, the intention is that an independent metrics
//! process will run (main loop in the controller mod), and receive requests via a tube from
//! another process.
//!
//! At head, metrics requests are ignored. However, a branching codebase can choose to implement
//! their own handler which processes and uploads metrics requests as it sees fit, by setting the
//! appropriate RequestHandler.
