There are 2 main differences from a normal *path operation*:

* It doesn't need to have any actual code, because your app will never call this code. It's only used to document the *external API*. So, the function could just have `pass`.

`FastAPI` doğrudan `Starlette`'i miras alan bir sınıftır.

<a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>'in tüm işlevselliğini `FastAPI` ile de kullanabilirsiniz.

### Adım 2: Bir `FastAPI` "Örneği" Oluşturalım

Burada `app` değişkeni `FastAPI` sınıfının bir örneği olacaktır.

Há 2 diferenças principais de uma *operação de rota* normal:

			recordDelimiter: []byte(args.RecordDelimiter),
			oneByte:         make([]byte, len(args.RecordDelimiter)-1),
		}
	}

	r := &Reader{
		args:       args,
		buf:        bufio.NewReaderSize(csvIn, csvSplitSize*2),
		readCloser: readCloser,
		close:      make(chan struct{}),
	}

	// Assume args are validated by ReaderArgs.UnmarshalXML()
	newCsvReader := func(r io.Reader) *csv.Reader {
		ret := csv.NewReader(r)

## CODEOWNERS style rules:
## 1. Prefer team ownership over individual user ownership.
## 2. GBT-related team should be listed first.
## 3. Try to keep paths alphabetically sorted within visual groups.
## 4. List individual owners last.

# bt-unassigned-maintainers must be the first owner
