Example 6 with CheckedRunnable

use of io.vavr.CheckedRunnable in project resilience4j by resilience4j.

the class TimerTest method shouldDecorateCheckedRunnableAndReturnWithSuccess.

@Test
public void shouldDecorateCheckedRunnableAndReturnWithSuccess() throws Throwable {
    // And measure the call with a Timer
