Enum Err 

pub enum Err {
    Len,
    Prefix,
    DuplicateName,
    UnknownName,
    UnknownMetric,
    MissingMandatoryMetrics,
    UnknownSeverity,
    InvalidMacroVector,
    UnknownVersion,
    UnknownNomenclature,
}

Parse or conversion error.

Examples

Try to parse an invalid vector string:

// try to parse invalid vector string, then the check result
assert_eq!("asdf".parse::<Vector>(), Err(Err::Len));

Convert an Err to a printable string:

assert_eq!(Err::DuplicateName.to_string(), "Vector string contains a duplicate metric name");

Variants

Len

String is too short to contain a CVSS vector string.

Example

// parse invalid string as vector, then check result
assert_eq!("asdf".parse::<Vector>(), Err(Err::Len));

Prefix

String does not begin with a CVSS: prefix.

Example

// parse invalid string as vector, then check result
assert_eq!("CVSS:foo/".parse::<Vector>(), Err(Err::Prefix));

DuplicateName

Vector string contains a duplicate metric name.

Example

// parse invalid string as vector, then check result
assert_eq!("CVSS:4.0/AV:N/AV:N".parse::<Vector>(), Err(Err::DuplicateName));

UnknownName

Unknown metric name.

Example

// parse unknown metric name, check result
assert_eq!("asdf".parse::<Name>(), Err(Err::UnknownName));

UnknownMetric

Vector string contains an unknown metric.

Example

// parse vector string with unknown metric value, then check result
assert_eq!("CVSS:4.0/AV:Z".parse::<Vector>(), Err(Err::UnknownMetric));

// parse vector string with unknown metric name, then check result
assert_eq!("CVSS:4.0/ZZ:Z".parse::<Vector>(), Err(Err::UnknownMetric));

MissingMandatoryMetrics

Vector string is missing mandatory metrics.

Example

// vector string missing mandatory metric
let s = "CVSS:4.0/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H";

// parse string, check result
assert_eq!(s.parse::<Vector>(), Err(Err::MissingMandatoryMetrics));

UnknownSeverity

Unknown severity name.

Example

// vector string missing mandatory metric
let s = "asdf";

// parse string, check result
assert_eq!(s.parse::<Severity>(), Err(Err::UnknownSeverity));

InvalidMacroVector

Invalid v4::MacroVector digit.

A digit of a v4::MacroVector is out of range.

Example

// parse unknown CVSS version, check result
assert_eq!(MacroVector::try_from(123456), Err(Err::InvalidMacroVector));

UnknownVersion

Unknown CVSS version.

Example

// parse unknown CVSS version, check result
assert_eq!("asdf".parse::<Version>(), Err(Err::UnknownVersion));

UnknownNomenclature

Unknown v4::Nomenclature.

Example

// parse unknown CVSS v4 nomenclature, check result
assert_eq!("asdf".parse::<Nomenclature>(), Err(Err::UnknownNomenclature));

Trait Implementations

impl Clone for Err

fn clone(&self) -> Err

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Err

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Err

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Err

fn eq(&self, other: &Err) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
