Struct Pkgrel

pub struct Pkgrel(String);

A pkgrel of a package

Pkgrel is used to indicate the build version of a package and is appended to a version, delimited by a "-" (e.g. -2 is added to 1.0.0 to form 1.0.0-2 which then orders newer than 1.0.0-1).

A Pkgrel wraps a String which is guaranteed to not start with a "0", to contain only numeric characters (optionally delimited by a single ".", which must be followed by at least one non-"0" numeric character).

Examples

use std::str::FromStr;

use alpm_types::Pkgrel;

assert!(Pkgrel::new("1".to_string()).is_ok());
assert!(Pkgrel::new("1.1".to_string()).is_ok());
assert!(Pkgrel::new("0".to_string()).is_err());
assert!(Pkgrel::new("0.1".to_string()).is_err());
assert!(Pkgrel::new("1.0".to_string()).is_err());

Implementations

impl Pkgrel

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

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

pub fn inner(&self) -> &str

Return a reference to the inner type

Trait Implementations

impl Clone for Pkgrel

fn clone(&self) -> Pkgrel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pkgrel

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

Formats the value using the given formatter.

impl Display for Pkgrel

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

Formats the value using the given formatter.

impl FromStr for Pkgrel

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

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

type Err = Error

The associated error which can be returned from parsing.

impl Ord for Pkgrel

fn cmp(&self, other: &Pkgrel) -> 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 Pkgrel

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

fn partial_cmp(&self, other: &Pkgrel) -> 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.
