base_score/base-score.rs
1//! Print score and base score for several vectors.
2//!
3//! # Description
4//!
5//! The `base_score()` method allows you to get the base score for [CVSS
6//! v2][cvss-v2] and [CVSS v3][cvss-v3] vectors. For [CVSS v4][cvss-v4]
7//! vectors the score returned by `base_score()` is identical to the
8//! score returned by `Score::from()`.
9//!
10//! # Usage
11//!
12//! ```sh
13//! cargo run --example base-score
14//! ```
