Struct Block 

pub struct Block {
    pub transactions: Vec<Transaction>,
    pub timestamp: u64,
    pub nonce: u64,
    pub meta: BlockMetadata,
}

Stores transaction, difficulties, its hash, and its nonce The hash can be often used for indexing, however can only be trusted if this node checked this block already

Fields

transactions: Vec<Transaction>

timestamp: u64

nonce: u64

meta: BlockMetadata

Implementations

impl Block

pub fn new_block_now( transactions: Vec<Transaction>, block_pow_difficulty: &[u8; 32], tx_pow_difficulty: &[u8; 32], previous_block: Hash, merkle_tree_root: &[u8; 32], address_inclusion_filter: AddressInclusionFilter, ) -> Self

Create a new block timestamped now, with a set of transactions, specifying transaction difficulty and block difficulty

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

Get this blocks hashing buffer required to mine this transaction. Essentially makes sure that any hash attached to this block is not included in the block hashing buffer WARNING: Slow

pub fn compute_pow(&mut self) -> Result<(), EncodeError>

👎Deprecated

Mine this block and attach its hash. DEPRECATED: This is single threaded and cannot be used for actual mining as proper, multi-threaded mining machines outperform this by absolute miles

pub fn check_meta(&self) -> Result<(), BlockError>

Checks if block meta is valid

pub fn check_completeness(&self) -> Result<(), BlockError>

Checks if this block is complete, and has all required fields to be valid on a blockchain

pub fn validate_block_hash(&self) -> Result<(), BlockError>

Checks if the attached block hash is valid

pub fn validate_difficulties( &self, real_block_pow_difficulty: &[u8; 32], real_tx_pow_difficulty: &[u8; 32], ) -> Result<(), BlockError>

Checks if the passed difficulties match the blocks difficulties (true = valid, false = invalid)

pub fn validate_merkle_tree(&self) -> Result<(), BlockError>

Check if merkle tree root is correctly calculated

pub fn validate_address_inclusion_filter(&self) -> Result<(), BlockError>

Check if inclusion filter is correctly calculated

pub fn address_count(&self) -> usize

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for Block

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate 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<__Context> Decode<__Context> for Block

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

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 Encode for Block

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Hash for Block

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 PartialEq for Block

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
