6/// A generic wrapper around any serializable request data that contains the nonce for a request.
7///
8/// Using `#[serde(flatten)]`, this allows any serializable request to have a nonce field added to
9/// its output.
10///
11/// Users are able to, but unlikely to need to use this at all as nonces are generated in the HTTP
12/// methods internal to [`CoreKrakenClient`].
