Crate claim

Assertion macros.

This crate provides additional assert macros to make testing a bit easier.

#![no_std] support

claim can be used in a no-std environments too.

Available macros

Note that same to core/std macros, all macros in this crate has the debug_* counterparts.

Macros

• assert_err
  Asserts that expression returns Err(E) variant.

  Asserts that first expression is less or equal than the second.
• assert_lt
  Asserts that first expression is less than the second.

  Asserts that expression matches any of the given variants.
• assert_none
  Asserts that expression returns None variant.
• assert_ok
  Asserts that expression returns Ok(T) variant.
• assert_ok_eq
  Asserts that expression returns Ok(T) variant and its value of T type equals to the right expression.
