Struct Pkgver

pub struct Pkgver(pub(crate) String);

A pkgver of a package

Pkgver is used to denote the upstream version of a package.

A Pkgver wraps a String, which is guaranteed to only contain alphanumeric characters, "_", "+" or ".", but to not start with a "_", a "+" or a "." character and to be at least one char long.

NOTE: This implementation of Pkgver is stricter than that of libalpm/pacman. It does not allow empty strings "", or chars that are not in the allowed set, or "." as the first character.

Examples

use std::str::FromStr;

use alpm_types::Pkgver;

assert!(Pkgver::new("1".to_string()).is_ok());
assert!(Pkgver::new("1.1".to_string()).is_ok());
assert!(Pkgver::new("foo".to_string()).is_ok());
assert!(Pkgver::new("0".to_string()).is_ok());
assert!(Pkgver::new(".0.1".to_string()).is_err());
assert!(Pkgver::new("_1.0".to_string()).is_err());
assert!(Pkgver::new("+1.0".to_string()).is_err());

Implementations

impl Pkgver

pub fn new(pkgver: String) -> Result<Self, Error>

Create a new Pkgver from a string and return it in a Result

pub fn inner(&self) -> &str

Return a reference to the inner type

pub fn segments(&self) -> VersionSegments<'_>

Return an iterator over all segments of this version.

Trait Implementations

impl Clone for Pkgver

fn clone(&self) -> Pkgver

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pkgver

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

Formats the value using the given formatter.

impl Display for Pkgver

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

Formats the value using the given formatter.

impl FromStr for Pkgver

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

Create a Pkgver from a string and return it in a Result

type Err = Error

The associated error which can be returned from parsing.

impl Ord for Pkgver

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

This block implements the logic to determine which of two package versions is newer or whether they’re considered equal.

This logic is surprisingly complex as it mirrors the current C-alpmlib implementation for backwards compatibility reasons. https://gitlab.archlinux.org/pacman/pacman/-/blob/a2d029388c7c206f5576456f91bfbea2dca98c96/lib/libalpm/version.c#L83-217

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 Pkgver

fn eq(&self, other: &Self) -> 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 Pkgver

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.
