Struct Version 

pub struct Version<'a> {

    pub minor: u64,
    pub patch: u64,
    pub pre_release: Option<PreRelease<'a>>,

}

A parsed SemVer version (Semantic Versioning 2.0.0).

use semver::{parse, Version};

let v = parse("1.2.3-alpha.1+build.42").unwrap();
assert_eq!(v.major, 1);
assert_eq!(v.minor, 2);
assert_eq!(v.patch, 3);

use semver::parse;

let a = parse(“1.0.0+build1”).unwrap(); let b = parse(“1.0.0+build2”).unwrap(); assert_eq!(a, b); // build metadata ignored

let a = parse(“1.0.0-alpha”).unwrap(); let b = parse(“1.0.0”).unwrap(); assert_ne!(a, b); // pre-release is significant assert!(a < b); // pre-release < release

Trait Implementations

impl<'a> Clone for Version<'a>

fn clone(&self) -> Version<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Version<'a>

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Version<'de>

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<'a> Display for Version<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Version<'a>

impl<'a> Ord for Version<'a>

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<'a> PartialEq for Version<'a>

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<'a> PartialOrd for Version<'a>

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<'a> Serialize for Version<'a>

Available on crate feature serde only.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
