### Tags with Enums { #tags-with-enums }

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

<project>
  <groupId>snapshot-test</groupId>
  <artifactId>maven-test-snapshot-resolving</artifactId>
  <packaging>jar</packaging>
  <repositories>
    <repository>
      <id>central</id>
      <name>Fake Maven Central Repository</name>
      <url>file://dummy</url>
    </repository>
  </repositories>
  <dependencies>
    <dependency>
      <groupId>snapshot-test</groupId>
      <artifactId>maven-snapshot-a</artifactId>

# This is more or less a workaround to make Depends and Security hashable
# as other tools that use them depend on that
# Ref: https://github.com/fastapi/fastapi/pull/14320

from fastapi import Depends, Security


def dep():
    pass


def test_depends_hashable():
    dep()  # just for coverage
    d1 = Depends(dep)
    d2 = Depends(dep)
    d3 = Depends(dep, scope="function")
    d4 = Depends(dep, scope="function")

    latch = new CountDownLatch(1);
    future = createListenableFuture(Boolean.TRUE, null, latch);
  }

  @Override
  protected void tearDown() throws Exception {

    // Make sure we have no waiting threads.
    latch.countDown();
  }

  /** Constructs a listenable future with a value available after the latch has counted down. */
  protected abstract <V> ListenableFuture<V> createListenableFuture(

                .build());
        options.addOption(Option.builder(ALSO_MAKE)
                .longOpt("also-make")
                .desc("If project list is specified, also build projects required by the list")
                .build());
        options.addOption(Option.builder(ALSO_MAKE_DEPENDENTS)
                .longOpt("also-make-dependents")

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
