More Asserts (for Rust).

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!",
);

lib.rs:

Small library providing some macros helpful for asserting. The API is very similar to the API provided by the stdlib's own assert_eq!, assert_ne!, debug_assert_eq!, and debug_assert_ne!.

When one of the assertions fails, it prints out a message like the following:

thread 'main' panicked at 'assertion failed: `left < right`
  left: `4`,
 right: `3`', src/main.rs:47:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

Example

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!",
);
