Struct rustc_version::Version

pub struct Version {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
    pub pre: Vec<Identifier>,
    pub build: Vec<Identifier>,
}

Represents a version number conforming to the semantic versioning scheme.

Fields

major: u64

The major version, to be incremented on incompatible changes.

minor: u64

The minor version, to be incremented when functionality is added in a backwards-compatible manner.

patch: u64

The patch version, to be incremented when backwards-compatible bug fixes are made.

pre: Vec<Identifier>

The pre-release version identifier, if one exists.

build: Vec<Identifier>

The build metadata, ignored when determining version precedence.

Methods

impl Version

fn parse(version: &str) -> Result<Version, SemVerError>

Parse a string into a semver object.

fn increment_patch(&mut self)

Increments the patch number for this Version (Must be mutable)

fn increment_minor(&mut self)

Increments the minor version number for this Version (Must be mutable)

As instructed by section 7 of the spec, the patch number is reset to 0.

fn increment_major(&mut self)

Increments the major version number for this Version (Must be mutable)

As instructed by section 8 of the spec, the minor and patch numbers are reset to 0

fn is_prerelease(&self) -> bool

Checks to see if the current Version is in pre-release status

Trait Implementations

impl PartialOrd<Version> for Version

fn partial_cmp(&self, other: &Version) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
