Function lenient_semver::parse

pub fn parse(input: &str) -> Result<Version, Error<'_>>

Parse a string slice into a Version. This parser does not require semver-specification conformant input and is more lenient in what it allows. The differenc include:

• Minor and Path are optional an default to 0 (e.g. "1" parses at "1.0.0")
• Pre-release identifier may be separated by . as well (e.g. "1.2.3.rc1" parses at "1.2.3-rc1")
• Some pre-release identifiers are parsed as build identifier (e.g. "1.2.3.Final" parses at "1.2.3+Final")

Examples

use semver::Version;

let version = lenient_semver::parse("1.2.3");
assert_eq!(version, Ok(Version::new(1, 2, 3)));

// examples of a version that would not be accepted by semver_parser
assert_eq!(
    lenient_semver::parse("1.2.M1").unwrap(),
    Version::parse("1.2.0-M1").unwrap()
);
assert!(Version::parse("1.2.M1").is_err());

assert_eq!(
    lenient_semver::parse("1").unwrap(),
    Version::parse("1.0.0").unwrap()
);
assert!(Version::parse("1").is_err());

assert_eq!(
    lenient_semver::parse("1.2.3.Final").unwrap(),
    Version::parse("1.2.3+Final").unwrap()
);
assert!(Version::parse("1.2.3.Final").is_err());
