Struct rchain_v1::rchain::Block

pub struct Block {
    pub(crate) transactions: Vec<Transaction>,
    prev_hash: Option<String>,
    hash: Option<String>,
    nonce: u128,
}

One single part of the blockchain. Basically contains a list of transactions

Fields

transactions: Vec<Transaction>

Actions that this block includes There has to be at least one

prev_hash: Option<String>

This actually connects the blocks together

hash: Option<String>

We store the hash of the block here also in order to save the last block from being tampered with later on

nonce: u128

Some arbitrary number which will be later used for Proof of Work

Methods

impl Block

pub fn new(prev_hash: Option<String>) -> Self

pub fn set_nonce(&mut self, nonce: u128)

Changes the nonce number and updates the hash

pub fn calculate_hash(&self) -> Vec<u8>

Will calculate the hash of the whole block including transactions Blake2 hasher

pub fn add_transaction(&mut self, transaction: Transaction)

Appends a transaction to the queue

pub fn get_transaction_count(&self) -> usize

Will return the amount of transactions

pub(crate) fn update_hash(&mut self)

Will update the hash field by including all transactions currently inside the public modifier is only for the demonstration of attacks

pub fn verify_own_hash(&self) -> bool

Checks if the hash is set and matches the blocks interna

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Block

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
