Struct SemVer 

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

A parsed semantic version (major.minor.patch[-pre]).

Fields

major: u32

Major version component.

minor: u32

Minor version component.

patch: u32

Patch version component.

pre: Option<String>

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

Implementations

impl SemVer

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

Construct a release version (no pre-release).

pub fn with_pre( major: u32, minor: u32, patch: u32, pre: impl Into<String>, ) -> Self

Construct a pre-release version.

pub fn parse(s: &str) -> Result<Self, ResolveError>

Parse a semver string such as "1.2.3" or "1.0.0-beta.2".

Errors

Returns a ResolveError::NotFound-wrapping string on parse failure.

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

Semver compatibility check: same major, self >= required.

This is the ^ (caret) / “compatible” definition.

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 Display for SemVer

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

Formats the value using the given formatter.

impl Hash for SemVer

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 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: &SemVer) -> 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.
