You put it on top of a function. Like a pretty decorative hat (I guess that's where the term came from).

A "decorator" takes the function below and does something with it.

In our case, this decorator tells **FastAPI** that the function below corresponds to the **path** `/` with an **operation** `get`.

It is the "**path operation decorator**".

You can also use the other operations:

* `@app.post()`

	vars := mux.Vars(r)
	bucket := vars["bucket"]

	objAPI := api.ObjectAPI()
	if objAPI == nil {
		writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrServerNotInitialized), r.URL)
		return
	}

	// Allow GetBucketWebsite if policy action is set, since this is a dummy call
	// we are simply re-purposing the bucketPolicyAction.
	if s3Error := checkRequestAuthType(ctx, r, policy.GetBucketPolicyAction, bucket, ""); s3Error != ErrNone {

	sep := []byte("/")
	for range b.N {
		for range SplitSeq(benchInputHard, sep) {
		}
	}
}

func BenchmarkSplitSeqMultiByteSeparator(b *testing.B) {
	sep := []byte("hello")
	for range b.N {
		for range SplitSeq(benchInputHard, sep) {
		}
	}
}

func BenchmarkSplitAfterSeqEmptySeparator(b *testing.B) {
	for range b.N {
		for range SplitAfterSeq(benchInputHard, nil) {
		}

	}

	err = fs.AppendFile(context.Background(), "voldir", "/file", []byte("hello"))
	if err != nil {
		t.Fatal(err)
	}

	// Try to create a file that includes a file in its path components.
	// In *nix, this returns syscall.ENOTDIR while in windows we receive the following error.
	err = fs.AppendFile(context.Background(), "voldir", "/file/obj1", []byte("hello"))
	if err != errFileAccessDenied {

What happened to you?  Tell us all about it!'

  Last came a little feeble, squeaking voice, (`That's Bill,'
thought Alice,) `Well, I hardly know--No more, thank ye; I'm
better now--but I'm a deal too flustered to tell you--all I know
is, something comes at me like a Jack-in-the-box, and up I goes
like a sky-rocket!'

  `So you did, old fellow!' said the others.
