Small library providing assertion macros similar to the {debug_,}assert_{eq,ne} macros in the stdlib.

Usage

use more_asserts as ma;

#[derive(Debug, PartialEq, PartialOrd)]
enum Example { Foo, Bar }

ma::assert_le!(3, 4);
ma::assert_ge!(
    10, 10,
    "You can pass a message too (just like `assert_eq!`)",
);
ma::debug_assert_lt!(
    1.3, 4.5,
    "Format syntax is supported ({}).",
    "also like `assert_eq!`"
);

ma::assert_gt!(
    Example::Bar, Example::Foo,
    "It works on anything that implements PartialOrd and Debug!",
);

License

Public domain as explained by either the Unlicense or CC0. If neither of these are acceptable, you can also choose use it under the MIT/Apache2 combo typical of Rust code.

Yes, this is a lot. It was originally just "public domain as explained by CC0" (since CC0 was the public domain-alike license preferred by lawyers), but then CC0 fell out of favor, so I added the others as alternatives: Unlicense as a (hopefully) better public domain analogue, and MIT/Apache2 since (I know some folks dislike the Unlicense and) Rust will implode if those ever become a problem.
