As a special case, C.malloc does not call the C library malloc directly
but instead calls a Go helper function that wraps the C library malloc
but guarantees never to return nil. If C's malloc indicates out of memory,
the helper function crashes the program, like when Go itself runs out
of memory. Because C.malloc cannot fail, it has no two-result form
that returns errno.

`aGVsbG8=` est l'encodage base64 de `hello`.

///

Pydantic décodera ensuite la chaîne base64 et vous fournira les octets originaux dans le champ `data` du modèle.

Vous recevrez une réponse comme :

```json
