Struct PackageRelease

pub struct PackageRelease {
    pub major: usize,
    pub minor: Option<usize>,
}

The release version of a package.

A PackageRelease wraps a usize for its major version and an optional usize for its minor version.

PackageRelease is used to indicate the build version of a package. It is mostly useful in conjunction with a PackageVersion (see Version). Refer to alpm-pkgrel for more details on the format.

Examples

use std::str::FromStr;

use alpm_types::PackageRelease;

assert!(PackageRelease::from_str("1").is_ok());
assert!(PackageRelease::from_str("1.1").is_ok());
assert!(PackageRelease::from_str("0").is_ok());
assert!(PackageRelease::from_str("a").is_err());
assert!(PackageRelease::from_str("1.a").is_err());

Fields

major: usize

The major version of this package release.

minor: Option<usize>

The optional minor version of this package release.

Implementations

impl PackageRelease

pub fn new(major: usize, minor: Option<usize>) -> Self

Creates a new PackageRelease from a major and optional minor integer version.

Examples

use alpm_types::PackageRelease;

let release = PackageRelease::new(1, Some(2));
assert_eq!(format!("{release}"), "1.2");

pub fn parser(input: &mut &str) -> ModalResult<Self>

Recognizes a PackageRelease in a string slice.

Consumes all of its input.

Errors

Returns an error if input does not contain a valid PackageRelease.

Trait Implementations

impl Clone for PackageRelease

fn clone(&self) -> PackageRelease

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackageRelease

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PackageRelease

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PackageRelease

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

Formats the value using the given formatter.

impl FromStr for PackageRelease

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

Creates a PackageRelease from a string slice.

Delegates to PackageRelease::parser.

Errors

Returns an error if PackageRelease::parser fails.

type Err = Error

The associated error which can be returned from parsing.

impl Ord for PackageRelease

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 PackageRelease

fn eq(&self, other: &PackageRelease) -> 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 PackageRelease

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.

impl Serialize for PackageRelease

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PackageRelease
