Class DmxRetry

java.lang.Object
dmx.fun.resilience4j.DmxRetry
@NullMarked public final class DmxRetry extends Object
dmx-fun adapter for Resilience4J Retry.

Executes a supplier through the configured retry policy and returns a dmx-fun type instead of throwing. Configure the retry using the native Resilience4J API: 

RetryConfig config = RetryConfig.custom()
    .maxAttempts(3)
    .waitDuration(Duration.ofMillis(200))
    .retryOnException(IOException.class::isInstance)
    .build();

DmxRetry retry = DmxRetry.of("my-retry", config);

Try<Response>               r1 = retry.executeTry(() -> httpClient.get(url));
Result<Response, Throwable> r2 = retry.executeResult(() -> httpClient.get(url));
