Struct TokenRef 

pub struct TokenRef(/* private fields */);

A reference to the contract token a session authenticated with — never the token itself.

An RFID UID or an eMAID identifies a natural person’s charging contract across every operator they visit. It is personal data under Art. 4 Nr. 1 GDPR, and the allocation does not need it: the allocation needs to know which virtual MaLo a session belongs to, which is a lookup the token registry performs once, upstream.

So this type carries an opaque, keyed hash produced by that registry. Nothing here can reverse it, and a leaked allocation ledger discloses no contract identities. Unknown tokens are not an error — they route to the Residual-MaLo.

Implementations

impl TokenRef

pub fn from_keyed_hash(hash: impl Into<String>) -> Self

Wrap a keyed hash produced by the token registry.

The caller is responsible for the keying; this type only guarantees that a raw token never reaches the allocation ledger by accident.

pub fn as_str(&self) -> &str

The wrapped hash.
