### Override the method { #override-the-method }

Now you can replace the `.openapi()` method with your new function.

### Check it { #check-it }

Once you go to [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) you will see that you are using your custom logo (in this example, **FastAPI**'s logo):

    fun CheckResult.assertBinaryCompatible() {
        assertTrue(richReport.toAssertionMessage("Expected to be compatible but the check failed"), isBinaryCompatible)
    }

    private
    fun CheckResult.assertNotBinaryCompatible() {
        assertFalse(richReport.toAssertionMessage("Expected to be breaking but the check passed"), isBinaryCompatible)
    }

    private
    fun RichReport.toAssertionMessage(message: String) =

        }
    }

    /**
     * Check if this exception is retryable
     *
     * @return true if the operation can be retried
     */
    public boolean isRetryable() {
        return errorCode.isRetryable() && retryPolicy != RetryPolicy.NO_RETRY;
    }

    /**
     * Check if retry should be attempted
     *
     * @param attemptNumber the current attempt number

 * ACE and <i>any</i> of the desired access bits match bits in the access
 * mask of the ACE, the whole access check fails. If the ACE is an "allow"
 * ACE and <i>all</i> of the bits in the desired access bits match bits in
 * the access mask of the ACE, the access check is successful. Otherwise,
 * more ACEs are evaluated until all desired access bits (combined)
