class HTTPAuthorizationCredentials(BaseModel):
    """
    The HTTP authorization credentials in the result of using `HTTPBearer` or
    `HTTPDigest` in a dependency.

    The HTTP authorization header value is split by the first space.

    The first part is the `scheme`, the second part is the `credentials`.

    For example, in an HTTP Bearer token scheme, the client will send a header
    like:

    ```
    Authorization: Bearer deadbeef12346

There's a high chance that the logic for your *startup* and *shutdown* is connected, you might want to start something and then finish it, acquire a resource and then release it, etc.

Doing that in separated functions that don't share logic or variables together is more difficult as you would need to store values in global variables or similar tricks.

Because of that, it's now recommended to instead use the `lifespan` as explained above.

		if disk == nil {
			continue
		}
		if di, err := disk.DiskInfo(ctx, opts); err == nil {
			res[i] = &di
		}
	}
	return res
}

// hasSpaceFor returns whether the disks in `di` have space for and object of a given size.
func hasSpaceFor(di []*DiskInfo, size int64) (bool, error) {
	// We multiply the size by 2 to account for erasure coding.
	size *= 2
	if size < 0 {

Em seguida, tente com o velho amigo do programador, o preenchimento automático do editor.

Você digita o primeiro parâmetro da função, `first_name`, depois um ponto (`.`) e, em seguida, pressiona `Ctrl + Space` para acionar a conclusão.

Mas, infelizmente, você não obtém nada útil:

### Adicionar tipos { #add-types }

Vamos modificar uma única linha da versão anterior.

		ret.FieldsPerRecord = -1
		// If LazyQuotes is true, a quote may appear in an unquoted field and a
		// non-doubled quote may appear in a quoted field.
		ret.LazyQuotes = true
		// We do not trim leading space to keep consistent with s3.
		ret.TrimLeadingSpace = false
		ret.ReuseRecord = true
		return ret
	}

	return r, r.startReaders(newCsvReader)

Sie übergeben es einfach an `Depends` und **FastAPI** weiß, wie der Rest erledigt wird.

In den Beispielen oben sehen Sie, dass es ein kleines bisschen **Codeverdoppelung** gibt.

    // fill empty space

    CacheTesting.drainRecencyQueues(cache);
    assertThat(keySet).containsExactly(0, 6, 7, 8, 15, 9);
