Module v4 

CVSS v4 parsing and scoring.

Examples

Parse CVSS v4 vector string, then get a Metric by Name:

// parse vector string
let v: Vector = "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H".parse()?;

// get metric
let metric = v.get(Name::AttackVector);

// check result
assert_eq!(metric, Metric::AttackVector(AttackVector::Network));

Build Vec of metric names:

// parse vector string
let v: Vector = "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H".parse()?;

// get metric names
let names: Vec<Name> = v.into_iter().map(Name::from).collect();

// check result
assert_eq!(names, vec![
  Name::AttackVector,
  Name::AttackComplexity,
  Name::AttackRequirements,
  Name::PrivilegesRequired,
  Name::UserInteraction,
  Name::VulnerableSystemConfidentialityImpact,
  Name::VulnerableSystemIntegrityImpact,
  Name::VulnerableSystemAvailabilityImpact,
  Name::SubsequentSystemConfidentialityImpact,
  Name::SubsequentSystemIntegrityImpact,
  Name::SubsequentSystemAvailabilityImpact,
]);

Get score for CVSS v4 vector string:

// parse vector string
let v: Vector = "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N".parse()?;

// get score
let score = Score::from(v);

// check result
assert_eq!(score, Score::from(6.9));
