//! Raft metrics for observability.
//!
//! Applications may use this data in whatever way is needed. The obvious use cases are to expose
//! these metrics to a metrics collection system like Prometheus. Applications may also
//! use this data to trigger events within higher levels of the parent application.
//!
//! Metrics are observed on a running Raft node via the `Raft::metrics()` method, which will
//! return a stream of metrics.
