Elements block header

Fields

version: u32

Version - should be 0x20000000 except when versionbits signalling

prev_blockhash: BlockHash

Previous blockhash

merkle_root: TxMerkleNode

Transaction Merkle root

time: u32

Block timestamp

height: u32

Block height

ext: ExtData

Block signature and dynamic federation-related data

Implementations

impl BlockHeader

pub fn block_hash(&self) -> BlockHash

Return the block hash.

pub fn is_dynafed(&self) -> bool

Returns true if this is a block with dynamic federations enabled.

pub fn clear_witness(&mut self)

Remove the witness data of the block header. This is all the data that can be removed without changing the block hash.

pub fn calculate_dynafed_params_root(&self) -> Option<Midstate>

Calculate the root of the dynafed params. Returns None when not dynafed.

pub fn dynafed_current(&self) -> Option<&Params>

Get the current dynafed parameters if it’s a dynafed header.

pub fn dynafed_proposed(&self) -> Option<&Params>

Get the proposed dynafed parameters if it’s a dynafed header.

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<D: Read>(d: D) -> Result<Self, Error>

Decode an object with a well-defined format

impl Encodable for BlockHeader

fn consensus_encode<S: Write>(&self, s: S) -> Result<usize, Error>

Encode an object with a well-defined format, should only ever error if the underlying Write errors. Returns the number of bytes written on success

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 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.
