Struct SemVer 

pub struct SemVer { /* private fields */ }

Semantic version in the form MAJOR.MINOR.PATCH with optional pre-release and build metadata identifiers.

Parses 1.2.3, 1.2.3-beta.1, 1.2.3+build.456, and 1.2.3-alpha.1+build.456.

Implementations

impl SemVer

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

Creates a SemVer with no pre-release or build metadata.

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

Parses a semver string.

pub fn major(&self) -> u64

Returns the major version component.

pub fn minor(&self) -> u64

Returns the minor version component.

pub fn patch(&self) -> u64

Returns the patch version component.

pub fn pre(&self) -> Option<&str>

Returns the pre-release identifier if present.

pub fn build(&self) -> Option<&str>

Returns the build metadata if present.

pub fn is_pre_release(&self) -> bool

Returns true if this is a pre-release version.

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

Compares semantic version precedence according to the SemVer rules.

Build metadata is ignored for SemVer precedence. This differs from Ord, which uses build metadata as a final tie-breaker so that Rust’s total ordering remains consistent with Eq.

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 Eq for SemVer

impl FromStr for SemVer

type Err = PrimitiveError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

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 PartialEq<&String> for SemVer

fn eq(&self, other: &&String) -> 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 PartialEq<&str> for SemVer

fn eq(&self, other: &&str) -> 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 PartialEq<String> for SemVer

fn eq(&self, other: &String) -> 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 PartialEq<str> for SemVer

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