//! ## Usage
//!
//! The [`Cvss`] type provides a unified interface for working with CVSS
//! vectors.
//!
//! The [`v3::Base`] type provides the main functionality currently implemented
//! for CVSS v3, namely: support for parsing, serializing, and scoring
//! `CVSS:3.0` and `CVSS:3.1` Base Metric Group vector strings as described in
//! the [CVSS v3.1 Specification].
//!
//! The [`v4::Vector`] type provides a fully-featured implementation of CVSS
//! v4.0, as described in the [CVSS v4.0 Specification].
//!
//! Serde support is available through the optional `serde` Cargo feature.
//!
//! [CVSS v3.1 Specification]: https://www.first.org/cvss/v3.1/specification-document
//! [CVSS v4.0 Specification]: https://www.first.org/cvss/v4.0/specification-document
