Struct PackageVersions 

pub struct PackageVersions { /* private fields */ }

It’s not enough to just track one version for each package, we need:

• The latest stable version (if any)
• The last version of each type of pre-release following the latest stable version

So we might have 1.2.3, 1.2.4-rc.1, 1.3.0-beta.0, and 2.0.0-alpha.4

Implementations

impl PackageVersions

pub fn from_tags<S: AsRef<str> + Debug>( prefix: Option<&str>, all_tags: &[S], ) -> Self

Get the (relevant) current versions from a slice of Git tags.

Tags are expected to either be v{version} or {prefix}/v{version} (if supplied),

Parameters

• prefix: Only tag names starting with this string will be considered.
• all_tags: All tags in the repository.

pub fn into_latest(self) -> Option<Version>

Consumes self to produce the most recent version (determined by order of tags).

pub fn bump(&mut self, rule: Rule) -> Result<Version, PreReleaseNotFound>

Apply a Rule to a [PackageVersion], incrementing & resetting the correct components.

Versions 0.x

Versions with major component 0 have special meaning in Semantic Versioning and therefore have different behavior:

1. [Rule::Major] will bump the minor component.
2. [Stable(Minor)] will bump the patch component.

Errors

Can fail if trying to run Rule::Release when there is no pre-release.

pub fn stable(&self) -> Option<StableVersion>

Trait Implementations

impl Clone for PackageVersions

fn clone(&self) -> PackageVersions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackageVersions

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

Formats the value using the given formatter.

impl Default for PackageVersions

fn default() -> PackageVersions

Returns the “default value” for a type.

impl From<StableVersion> for PackageVersions

fn from(version: StableVersion) -> Self

Converts to this type from the input type.

impl From<Version> for PackageVersions

fn from(version: Version) -> Self

Converts to this type from the input type.

impl PartialEq for PackageVersions

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