A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

// =============================================================================
// Implementation detail for the unified execution APIs for Eager and tracing
// backends (graph/MLIR).
//
// This defines a set of abstract classes that are intended to provide the
// functionality of the opaque C types exposed in the public APIs defined in the
// `c_api_unified_experimental.h` header.

          public void onFailure(Throwable t) {}
        },
        directExecutor());
    assertThat(called[0]).isTrue();
  }

  // Avoid trouble with automatic mapping between JRE and Kotlin runtime classes.
  static class CustomRuntimeException extends RuntimeException {}

  public void testCatching() throws Exception {
    FluentFuture<?> f =
        FluentFuture.from(immediateFailedFuture(new CustomRuntimeException()))

// Tests validate correctness of PutObject.
func testObjectAPIPutObject(obj ObjectLayer, instanceType string, t TestErrHandler) {
	// Generating cases for which the PutObject fails.
	bucket := "minio-bucket"
	object := "minio-object"

	// Create bucket.
	err := obj.MakeBucket(context.Background(), bucket, MakeBucketOptions{})
	if err != nil {

  }

  @LazyInit private transient @Nullable UnmodifiableSortedMultiset<E> descendingMultiset;

  // TODO(b/418181860): This method creates retain cycles in J2ObjC. In order to break the cycle,
  // there needs to be separate classes for primary and descending multiset, where the primary one
  // would hold {@code @LazyInit @RetainedWith @Nullable} reference to its descending multiset, and
  // the other {@code final} reference.
  @Override

        return connection.getContent();
    }

    @Override
    public Object getContent(final Class[] classes) throws IOException {
        try {
            handshake();
        } catch (final IOException ex) {}
        return connection.getContent(classes);
    }

    @Override
    public Permission getPermission() throws IOException {
        return connection.getPermission();
    }

      return ByteStreams.readBytes(in, processor);
    } catch (Throwable e) {
      throw closer.rethrow(e);
    } finally {
      closer.close();
    }
  }

  /**
   * Hashes the contents of this byte source using the given hash function.
   *
   * @throws IOException if an I/O error occurs while reading from this source
   */
  public HashCode hash(HashFunction hashFunction) throws IOException {

        across a similar need in our own work, that's extremely helpful in studying how broadly
        useful the proposed change will be.
