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.
