Struct Version 

pub struct Version { /* private fields */ }

Represents a RubyGems version with full semantic compatibility.

Implements the same parsing and comparison rules as Ruby’s Gem::Version:

• Dot-separated segments (numeric and string)
• Trailing zeros are ignored in comparisons (1.0 == 1.0.0)
• String segments denote pre-release versions
• Pre-release versions sort before their release counterparts

Examples

use gem_audit::version::Version;

let v1 = Version::parse("1.2.3").unwrap();
let v2 = Version::parse("1.2.4").unwrap();
assert!(v1 < v2);

let pre = Version::parse("1.0.0.alpha").unwrap();
let release = Version::parse("1.0.0").unwrap();
assert!(pre < release);

Implementations

impl Version

pub fn parse(input: &str) -> Result<Self, VersionError>

Parse a version string into a Version.

Follows RubyGems parsing rules:

• Segments are split by .
• Within each segment, numeric and alphabetic parts are separated
• Leading zeros in numeric segments are stripped
• Hyphens are converted to .pre.
• Empty string becomes version “0”

pub fn is_prerelease(&self) -> bool

Returns true if this version is a pre-release.

A version is pre-release if any of its segments is a string.

pub fn bump(&self) -> Version

Bump this version: drop the last segment and increment the new last segment.

This is equivalent to Ruby’s Gem::Version#bump:

• 1.2.3.bump() -> 1.3
• 1.0.bump() -> 2
• 1.bump() -> 2

pub fn segments(&self) -> &[Segment]

Returns the segments of this version.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Formats the value using the given formatter.

impl Ord for Version

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Version

fn eq(&self, other: &Self) -> 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.

impl PartialOrd for Version

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
