| //! This test verifies that `std::num::TryFromIntError` correctly implements `PartialEq`, |
| //! allowing `Result<T, TryFromIntError>` values to be compared for equality using `==`. |
| //! It specifically checks a successful numeric conversion scenario where the `Result::Ok` |
| //! variant is compared, ensuring that the comparison yields the expected boolean result. |
| |
| //@ run-pass |

| #![allow(unused_must_use)] // Allow ignoring the result of the comparison for the test's purpose |
