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.
assert_ge	Asserts that first expression is greater or equal than the second.
assert_gt	Asserts that first expression is greater than the second.
assert_le	Asserts that first expression is less or equal than the second.
assert_lt	Asserts that first expression is less than the second.
assert_matches	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.
assert_pending	Asserts that expression returns Poll::Pending variant.
