Macros§

assert_err
Asserts that the expression matches an Err(_) variant, returning the contained value.
assert_err_eq
Asserts that the left expression contains an Err(E) variant and its contained value of type E equals the right expression.
assert_ge
Asserts that the first expression is greater than or equal to the second.
assert_gt
Asserts that the first expression is greater than the second.
assert_le
Asserts that the first expression is less or equal than the second.
assert_lt
Asserts that the first expression is less than the second.
assert_matches
Asserts that the expression matches the provided pattern.
assert_none
Asserts that the expression is None.
assert_ok
Asserts that the expression matches an Ok(_) variant, returning the contained value.
assert_ok_eq
Asserts that the left expression contains an Ok(T) variant and its contained value of type T equals the right expression.
assert_pending
Asserts that the expression matches a Poll::Pending variant.
