//! Advanced extension points for the Cadence library
//!
//! Most users of Cadence shouldn't need to make use of this module or
//! the included traits and types. However, users that need to extend the
//! library in unforeseen ways may find them useful.
//!
//! The `MetricBackend` trait, for example, can be used to implement a
//! client that sends a new non-standard type of metric using the same
//! backend that Cadence would use (via the `.send_metric()` method).
//!
//! The various `To*Value` traits are used as markers for types that are
//! valid for each type of metric. They also contain conversion logic for
//! the types in some cases (such as in the case of `Duration` objects).
//! These can be used to allow your own custom types to be converted to
//! metric values that Cadence understands.
//!
//! In summary, most users don't need to worry about these types but they
//! are available for advanced use cases and subject to the same guarantees
//! as the rest of the API (semantic versioning, etc.).
