//! # Cantal Client
//!
//! [Documentation](https://docs.rs/tk-cantal) |
//! [Github](https://github.com/tailhook/tk-cantal) |
//! [Crate](https://crates.io/crates/tk-cantal)
//!
//! This client is usually used to find out peers known to cantal, i.e. peers
//! of the current cluster.
//!
//! This is **not** a way to submit metrics to cantal. See [`libcantal`] for
//! that.
//!
//! We will expose more APIs, like fetching metrics later.
