Fields

version: u32

Block version, now repurposed for soft fork signalling.

prev_blockhash: BlockHash

Reference to the previous block in the chain.

merkle_root: TxMerkleNode

The root hash of the merkle tree of transactions in the block.

time: u32

The timestamp of the block, as claimed by the miner.

bits: u32

The target value below which the blockhash must lie.

nonce: u32

The nonce, selected to obtain a low enough blockhash.

Trait Implementations

impl Clone for BlockHeader

fn clone(&self) -> BlockHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHeader

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

Formats the value using the given formatter.

impl Decodable for BlockHeader

fn consensus_decode_from_finite_reader<R: BufRead + ?Sized>( r: &mut R, ) -> Result<Self, Error>

Decode Self from a size-limited reader.

fn consensus_decode<R>(reader: &mut R) -> Result<Self, Error>

where R: BufRead + ?Sized,

Decode an object with a well-defined format.

impl Encodable for BlockHeader

fn consensus_encode<W: Write + ?Sized>(&self, w: &mut W) -> Result<usize, Error>

Encodes an object with a well-defined format.

impl From<&BlockHeader> for BlockHash

fn from(header: &BlockHeader) -> BlockHash

Converts to this type from the input type.

impl From<BlockHeader> for BlockHash

fn from(header: BlockHeader) -> BlockHash

Converts to this type from the input type.

impl Hash for BlockHeader

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 Ord for BlockHeader

fn cmp(&self, other: &BlockHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for BlockHeader

fn eq(&self, other: &BlockHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for BlockHeader

fn partial_cmp(&self, other: &BlockHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
