Vamos supor que o arquivo dedicado a lidar apenas com usuários seja o submódulo em `/app/routers/users.py`.

Você quer manter as *operações de rota* relacionadas aos seus usuários separadas do restante do código, para mantê-lo organizado.

Mas ele ainda faz parte da mesma aplicação/web API **FastAPI** (faz parte do mesmo "pacote Python").

//  arguments are as follows:
//
//    ncontrol_outputs: Number of control outputs of the function.
//    control_outputs: vector of TF_Operation objects to be marked as control
//      outputs of the function. Operations marked as control outputs are
//      guaranteed to execute.
//    control_output_names: Optional. If not nullptr, vector of strings, one

// A chunk has the following format:
//
//	<chunk-size-as-hex> + ";chunk-signature=" + <signature-as-hex> + "\r\n" + <payload> + "\r\n"
//
// First, we read the chunk size but fail if it is larger
// than 16 MiB. We must not accept arbitrary large chunks.
// One 16 MiB is a reasonable max limit.
//
// Then we read the signature and payload data. We compute the SHA256 checksum
