pub struct CompareVersion;

Implementations

impl CompareVersion

pub fn compare_version( version1: &str, version2: &str, ) -> Result<VersionComparison, VersionError>

Compares two version strings and returns a VersionComparison enum.

Arguments

• version1 - A string slice that holds the first version to compare.
• version2 - A string slice that holds the second version to compare.

Errors

Returns a VersionError if either version cannot be parsed.

Examples

use compare_version::*;
let result = CompareVersion::compare_version("1.2.3", "1.2.4");
assert_eq!(result, Ok(VersionComparison::Less));

pub fn matches_version_range( version: &str, range: &str, ) -> Result<bool, VersionError>

Checks whether a version matches a specified range, supporting ^ and ~ ranges.

Arguments

• version - A string slice that holds the version to check against the range.
• range - A string slice that holds the version range to check.

Errors

Returns a VersionError if the version or range cannot be parsed.

Examples

use compare_version::*;
let matches = CompareVersion::matches_version_range("1.2.3", "^1.2.0");
assert_eq!(matches, Ok(true));

use compare_version::*;
let matches = CompareVersion::matches_version_range("1.2.3", "~1.2.4");
assert_eq!(matches, Ok(false));
