Fields

version: i32

Block version, now repurposed for soft fork signalling.

prev_block_hash: BlockHash

Reference to the previous block in the chain.

merkle_root: BlockMerkleRoot

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.

type Err = BlockDataParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<BlockHeader, <BlockHeader as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for BlockHeader

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

where __H: Hasher,

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 LowerHex for BlockHeader

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

Formats the value using the given formatter.

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,

Restrict a value to a certain interval.

impl PartialEq for BlockHeader

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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