Struct SemVer 

pub struct SemVer {
    pub major: u32,
    pub minor: u32,
    pub patch: u32,
    pub pre_release: Option<String>,
    pub build_metadata: Option<String>,
}

A Semantic Versioning 2.0 version triple plus optional pre-release and build-metadata labels.

Ordering and equality are based solely on (major, minor, patch).

Fields

major: u32

Major version — breaking changes.

minor: u32

Minor version — backward-compatible new features.

patch: u32

Patch version — backward-compatible bug fixes.

pre_release: Option<String>

Optional pre-release identifier (e.g. "alpha", "beta.1").

build_metadata: Option<String>

Optional build metadata (e.g. "build.1", "20240101").

Implementations

impl SemVer

pub fn new(major: u32, minor: u32, patch: u32) -> Self

Construct a new version without pre-release or build metadata.

pub fn parse(s: &str) -> Result<SemVer, SemVerError>

Parse a SemVer string such as "1.2.3", "1.2.3-alpha", "1.2.3+build.1", or "1.2.3-alpha+build".

pub fn bump_major(&self) -> SemVer

Increment the major version and zero out minor and patch. Clears pre-release and build metadata.

pub fn bump_minor(&self) -> SemVer

Increment the minor version and zero out patch. Clears pre-release and build metadata.

pub fn bump_patch(&self) -> SemVer

Increment the patch version. Clears pre-release and build metadata.

pub fn is_compatible_with(&self, other: &SemVer) -> bool

Returns true when self is compatible with other: same major version AND self >= other.

Trait Implementations

impl Clone for SemVer

fn clone(&self) -> SemVer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemVer

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

Formats the value using the given formatter.

impl Default for SemVer

fn default() -> Self

Returns the “default value” for a type.

impl Display for SemVer

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

Formats the value using the given formatter.

impl Eq for SemVer

impl Ord for SemVer

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 SemVer

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 SemVer

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.
