Struct Block

pub struct Block<T: Hash> {
    pub id: u64,
    pub value: T,
    pub previous_id: u64,
    pub timestamp: DateTime<Utc>,
}

A Block representation.

Fields

id: u64

An height identifier of the given Block.

value: T

A binding of the given Block.

previous_id: u64

An identifier of the previous Block in the Chain.

timestamp: DateTime<Utc>

A timespec that the given Block was created.

Implementations

impl<T: Hash> Block<T>

pub fn new(id: u64, value: T, previous_id: u64) -> Block<T>

Creates a new Block.

pub fn is_trusty_for(&self, other: &Block<T>) -> bool

Returns true if the given Block is trusty for the next Block.

Examples

use libblockchain::Block;

let block0 = Block::new(0, vec![0; 256], 0);
let block1 = block0.next(vec![1, 2]);

assert!(block1.is_trusty_for(&block0))

pub fn next(&self, value: T) -> Block<T>

Constructs the next Block.

Examples

use libblockchain::Block;

let block0 = Block::new(0, vec![0; 256], 0);
let block1 = block0.next(vec![1, 2]);

println!("{:?}", block1)

Trait Implementations

impl<T: Clone + Hash> Clone for Block<T>

fn clone(&self) -> Block<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Hash> Debug for Block<T>

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

Formats the value using the given formatter.

impl<T: Hash + Hash> Hash for Block<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq + Hash> PartialEq for Block<T>

fn eq(&self, other: &Block<T>) -> 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.
