version_compare

Function compare

Source 
pub fn compare<A, B>(a: A, b: B) -> Result<Cmp, ()>
where
    A: AsRef<str>,
    B: AsRef<str>,
Expand description

Compare two version number strings to each other.

This compares version a to version b, and returns whether version a is greater, less or equal to version b.

If either version number string is invalid an error is returned.

One of the following operators is returned:

  • Cmp::Eq
  • Cmp::Lt
  • Cmp::Gt

§Examples

use version_compare::{Cmp, compare};

assert_eq!(compare("1.2.3", "1.2.3"), Ok(Cmp::Eq));
assert_eq!(compare("1.2.3", "1.2.4"), Ok(Cmp::Lt));
assert_eq!(compare("1", "0.1"), Ok(Cmp::Gt));
