option-extra

About

Additional utilities for common standard types, that feel missing.

Usage

New methods live in the OptionExt / ResultExt traits:

use option_extra::OptionExt;

assert_eq!(Some(1).zip_lazy(|| Some("abcd")), Some((1, "abcd")));

use option_extra::ResultExt;

assert!(Ok::<_, ()>(1).satisfies(|&n| n % 2 == 1));
