more-asserts 0.1.0

Small library providing additional assert and debug_assert macros.

More Asserts

Small library providing some macros helpful for asserting.


Use this crate by adding a #[macro_use] extern crate more_asserts to your code after adding it as a dependency.

The following macros are provided.

  • assert_ne!(left, right): Panics if !(left != right).
  • assert_lt!(left, right): Panics if !(left < right).
  • assert_gt!(left, right): Panics if !(left > right).
  • assert_le!(left, right): Panics if !(left <= right).
  • assert_ge!(left, right): Panics if !(left >= right).
  • debug_assert_ne!(left, right): Variant of assert_ne! controlled by cfg!(debug_assertions).
  • debug_assert_lt!(left, right): Variant of assert_lt! controlled by cfg!(debug_assertions).
  • debug_assert_gt!(left, right): Variant of assert_gt! controlled by cfg!(debug_assertions).
  • debug_assert_le!(left, right): Variant of assert_le! controlled by cfg!(debug_assertions).
  • debug_assert_ge!(left, right): Variant of assert_ge! controlled by cfg!(debug_assertions).
  • debug_unreachable!(...): Variant of the standard library's unreachable! that is controlled by cfg!(debug_assertations). Usful mainly when reaching the code is a bug that you absolutely want to know about, but there's a sane way to proceed in production code regardless. Forwards any arguments passed to it to unreachable!.

Note that assert_eq! and debug_assert_eq! are not provided as those are in the standard library.
