Enum version_number::Version

pub enum Version {
    Base(BaseVersion),
    Full(FullVersion),
}

A numbered version which is a two-component major.minor version number, or a three-component major.minor.patch version number.

Variants

Base(BaseVersion)

A two-component major.minor version.

Full(FullVersion)

A three-component major.minor.patch version.

Implementations

impl Version

pub fn parse(input: &str) -> Result<Self, Error>

Parse a two- or three-component, major.minor or major.minor.patch respectively, version number from a given input.

Returns a Error::ParserError if it fails to parse.

pub fn new_base_version(major: u64, minor: u64) -> Self

Create a new two-component major.minor version number.

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

Create a new three-component major.minor.patch version number.

pub fn major(&self) -> u64

Returns the major version component.

Both the two- and three-component version number variants have a major version. This is the leading component.

pub fn minor(&self) -> u64

Returns the minor version component.

Both the two- and three-component version number variants have a minor version. This is the middle component.

pub fn patch(&self) -> Option<u64>

Returns the patch version component, if any.

A three component major.minor.patch version will return a Some(<version>), while a two component major.minor version will return None instead.

If it exists, it is the last component.

pub fn is(&self, variant: Variant) -> bool

Check of which variant self is.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Formats the value using the given formatter.

impl From<(u64, u64)> for Version

fn from(tuple: (u64, u64)) -> Self

Converts to this type from the input type.

impl From<(u64, u64, u64)> for Version

fn from(tuple: (u64, u64, u64)) -> Self

Converts to this type from the input type.

impl FromStr for Version

type Err = Error

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Error>

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

impl Hash for Version

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 PartialEq<Version> for Version

fn eq(&self, other: &Version) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
