Struct Version 

pub struct Version {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
    pub pre: Option<String>,
    pub build: Option<String>,
    pub extension: Option<String>,
}

SemVer 2.0.0 compatible version with optional pre-release + build metadata. Major / minor / patch are required; everything past is optional + language-specific extension hooks live in extension.

Fields

major: u64

minor: u64

patch: u64

pre: Option<String>

1.2.3-rc.1 → Some("rc.1"). Empty string is not legal — use None to indicate no pre-release.

build: Option<String>

1.2.3+build.42 → Some("build.42"). Build metadata is version-comparison-irrelevant per SemVer (used only for display).

extension: Option<String>

Language-specific extension (e.g. RubyGems has a 4th segment; Python’s PEP-440 has epoch + post + dev). Adapter-owned — the engine doesn’t interpret this for comparison purposes.

Implementations

impl Version

pub const fn new(major: u64, minor: u64, patch: u64) -> Self

Canonical constructor for MAJOR.MINOR.PATCH (no pre / build).

pub fn parse(s: &str) -> Option<Self>

Parse a SemVer-shaped string. Returns None on malformed input — adapters that need a typed error should validate at their boundary.

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<'de> Deserialize<'de> for Version

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Version

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

Formats the value using the given formatter.

impl Hash for Version

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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: &Version) -> 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.

impl Serialize for Version

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Version
