// A TrustTokenStore provides operations on persistent state necessary for
// the various steps of the Trust TrustTokens protocol.
//
// For more information about the protocol, see the explainer at
// https://github.com/WICG/trust-token-api.
//
// TrustTokenStore translates operations germane to different steps
// of token issuance, token redemption, and request signing into
// operations in the key-value representation used by the persistence
// layer.
//
// For example, it provides operations:
// - checking preconditions for the different protocol steps;
// - storing unblinded, signed tokens; and
// - managing Redemption Records (RRs).
//
// TrustTokenStore's methods do minimal precondition checking and, in
// particular, only selectively verify protocol-level invariants and
// input integrity.
