Struct Transaction 

pub struct Transaction {
    pub inputs: Vec<TransactionInput>,
    pub outputs: Vec<TransactionOutput>,
    pub transaction_id: Option<TransactionId>,
    pub nonce: u64,
    pub timestamp: u64,
}

A transaction containing transaction inputs (funding this transaction) and outputs (spending this transactions funds) The transaction id is a way of finding this transaction once it becomes part of this blockchain. It is also the transaction id that is the actual Hash of the transaction buffer obtained by get_tx_hashing_buf The timestamp is set by the sender, and only loosely validated The nonce is also set by the sender to allow the transaction to be mined (POW)

Fields

inputs: Vec<TransactionInput>

outputs: Vec<TransactionOutput>

transaction_id: Option<TransactionId>

nonce: u64

timestamp: u64

Implementations

impl Transaction

pub fn new_transaction_now( inputs: Vec<TransactionInput>, outputs: Vec<TransactionOutput>, signing_keys: &mut Vec<Private>, ) -> Result<Self, EncodeError>

Create a new transaction timestamped now with a set of inputs and outputs. Signed automatically with the signing_keys (in same order as transaction inputs) WARNING: The transaction still needs to be mined (POW)! compute_pow() must be called after

pub fn compute_pow( &mut self, tx_difficulty: &[u8; 32], difficulty_margin: Option<f64>, ) -> Result<(), EncodeError>

Mine this transaction (aka. compute POW to allow it to be placed in the network) WARNING: This is single threaded and needs to complete before a new block is mined on the network as otherwise tx_difficulty becomes invalid, and so the transaction too Difficulty margin can be used to prevent the behavior mentioned above, however it will lead to a longer compute time. The bugger difficulty margin is, the more likely is the transaction to be valid next block. Difficulty margin is a multiplier by how much harder does the actual difficulty need to be

pub fn get_input_signing_buf(&self) -> Result<Vec<u8>, EncodeError>

Get the buffer that needs to be signed by each inputs private key

pub fn get_tx_hashing_buf(&self) -> Result<Vec<u8>, EncodeError>

Get the buffer that needs to be hashed to compute the pow puzzle
