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.
• assert_ready
  Asserts that the expression matches a Poll::Ready(_) variant.
• assert_ready_eq
  Asserts that the left expression contains a [Poll::Ready(T)] variant and its contained value of type T equals the right expression.
• assert_ready_err
  Asserts that the expression matches a Poll::Ready(Err(_)) variant, returning the contained value.
• assert_ready_ok
  Asserts that the expression matches a [Poll::Ready(Ok(_))] variant, returning the contained value.
• assert_some
  Asserts that the expression matches a Some(_) variant, returning the contained value.
• assert_some_eq
  Asserts that the left expression contains a Some(T) variant and its contained value of type T equals the right expression.
• debug_assert_err
  Asserts that the expression matches an Err(_) variant in debug builds.
• debug_assert_err_eq
  Asserts that the left expression contains an Err(E) variant and its contained value of type E equals the right expression in debug builds.
• debug_assert_ge
  Asserts that the first expression is greater than or equal to the second on debug builds.
• debug_assert_gt
  Asserts that the first expression is greater than the second in debug builds.

• debug_assert_ready
  Asserts that the expression matches a Poll::Ready(_) variant on debug builds.
• debug_assert_ready_eq
  Asserts that the left expression contains a Poll::Ready(T) variant and its contained value of type T equals the right expression on debug builds.
• debug_assert_ready_err
  Asserts that the expression matches a Poll::Ready(Err(_)) variant on debug builds.
