Struct damn_vuln_blockchain::block::Block

pub struct Block { /* fields omitted */ }

Smallest data-sctructure that can go into Chain.

NOTE: tx, prev, validator and rx are Option<_> to accomodate genesis block. Blockchain implementors must check for the existence of genesis block before appending the block to the ledger

Implementations

impl Block

pub fn to_string(&self) -> String

Get block info as string

pub fn genesis() -> Block

creates genesis block

pub fn is_genesis(&self) -> bool

checks if the block is a genesis block

pub fn hash(&self) -> String

computes the hash of a block, uses the same logic for genesis blocks, it simply returns the hash stored in the block as genesis() computes hash over random strings

pub fn get_prev(&self) -> Option<&String>

get hash of previous block

pub fn get_asset_id(&self) -> Option<&String>

get hash of previous block

pub fn get_hash(&self) -> &str

get hash of block

pub fn get_serial_no(&self) -> Option<usize>

get serial numbr of block

pub fn set_serial_no(&mut self, serial_no: usize)

set serial_no of block

pub fn get_rx(&self) -> Option<&String>

get receiver involved in the transaction that lead tot the creation of this block

pub fn get_validator(&self) -> Option<&String>

get validator involved in the creation of this block

pub fn get_tx(&self) -> Option<&String>

get sender involved in the transaction that lead tot the creation of this block

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.

impl Default for Block

fn default() -> Block

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Block

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

Deserialize this value from the given Serde deserializer.

impl Display for Block

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

Formats the value using the given formatter.

impl Serialize for Block

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

Serialize this value into the given Serde serializer.
