Struct Transaction 

pub struct Transaction {
    pub destination: Did,
    pub tx_id: Uuid,
    pub data: Vec<u8>,
    pub verification: MessageVerification,
}

All messages transmitted in RingsNetwork should be wrapped by Transaction. It additionally offer destination, tx_id and verification.

To transmit Transaction in RingsNetwork, user should build MessagePayload and use PayloadSender to send.

Fields

destination: Did

The destination of this message.

tx_id: Uuid

The transaction ID. Remote peer should use same tx_id when response.

data: Vec<u8>

data

verification: MessageVerification

This field holds a signature from a node, which is used to prove that the transaction was created by that node.

Implementations

impl Transaction

pub fn new<T>( destination: Did, tx_id: Uuid, data: T, session_sk: &SessionSk, ) -> Result<Transaction, Error>

where T: Serialize,

Wrap data. Will serialize by bincode::serialize then sign MessageVerification by session_sk.

pub fn data<T>(&self) -> Result<T, Error>

where T: DeserializeOwned,

Deserializes the data field into a T instance.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transaction

fn fmt(&self, __f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>( __deserializer: __D, ) -> Result<Transaction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Transaction

impl MessageVerificationExt for Transaction

fn verification_data(&self) -> Result<Vec<u8>, Error>

Give the data to be verified.

fn verification(&self) -> &MessageVerification

Give the verification field for verifying.

fn is_expired(&self) -> bool

Checks whether the message is expired.

fn verify(&self) -> bool

Verifies that the message is not expired and that the signature is valid.

fn signer(&self) -> Did

Get signer did from verification.

impl PartialEq for Transaction

fn eq(&self, other: &Transaction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Transaction

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
