Enum alpm_types::VersionComparison

pub enum VersionComparison {
    Less,
    LessOrEqual,
    Equal,
    GreaterOrEqual,
    Greater,
}

Specifies the comparison function for a VersionRequirement.

The package version can be required to be:

• less than (<)
• less than or equal to (<=)
• equal to (=)
• greater than or equal to (>=)
• greater than (>) than the specified version.

Variants

Less

LessOrEqual

Equal

GreaterOrEqual

Greater

Implementations

impl VersionComparison

fn is_compatible_with(self, ord: Ordering) -> bool

Returns true if the result of a comparison between the actual and required package versions satisfies the comparison function.

Examples

use alpm_types::{Version, VersionComparison};

let actual_version = Version::new("1.3").unwrap();

let required_version = Version::new("1.5").unwrap();
let required_comparison = VersionComparison::GreaterOrEqual;

let comparison = actual_version.cmp(&required_version);

assert!(!required_comparison.is_compatible_with(comparison));

Trait Implementations

impl Clone for VersionComparison

fn clone(&self) -> VersionComparison

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VersionComparison

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

Formats the value using the given formatter.

impl FromStr for VersionComparison

type Err = Error

The associated error which can be returned from parsing.

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

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

impl PartialEq for VersionComparison

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