tiny.machine.ContractFingerprint

1/// The identity of the shared execution rules. A caller compares this fingerprint2/// to know whether two profiles obey the same execution rules. The fingerprint is3/// computed over the profile's encoded form with the backend field and the four4/// claim fields zeroed, so the backend and the claims contribute nothing. A KVM5/// profile and its portable counterpart therefore hold the same value, so a test6/// can run both and compare what comes out. Restoring an instance from a checkpoint7/// requires this fingerprint to equal the one recorded in the checkpoint's receipt8/// basis. `hex` renders the digest as lowercase hexadecimal.9pub const ContractFingerprint = struct {10    digest: [Sha256.digest_length]u8,1112    pub fn hex(self: ContractFingerprint) [Sha256.digest_length * 2]u8 {13        return std.fmt.bytesToHex(self.digest, .lower);14    }15};
