impl Block

pub fn new_advanced_builder() -> BlockBuilder

Creates an empty advanced builder.

pub fn as_advanced_builder(&self) -> BlockBuilder

impl Block

pub fn into_view_without_reset_header(self) -> BlockView

Notice

BlockView created by this method could have invalid hashes or invalid merkle roots in the header.

pub fn into_view(self) -> BlockView

Calculates transaction associated hashes, resets all hashes and merkle roots in the header, then converts them into BlockView.

impl Block

pub fn calc_header_hash(&self) -> Byte32

Calls BlockReader.calc_header_hash() for self.as_reader().

impl Block

pub fn calc_proposals_hash(&self) -> Byte32

Calls BlockReader.calc_proposals_hash() for self.as_reader().

impl Block

pub fn calc_uncles_hash(&self) -> Byte32

Calls BlockReader.calc_uncles_hash() for self.as_reader().

impl Block

pub fn calc_extension_hash(&self) -> Option<Byte32>

Calls BlockReader.calc_extension_hash() for self.as_reader().

impl Block

pub fn calc_extra_hash(&self) -> ExtraHashView

Calls BlockReader.calc_extra_hash() for self.as_reader().

impl Block

pub fn calc_tx_hashes(&self) -> Vec<Byte32>

Calls BlockReader.calc_tx_hashes() for self.as_reader().

impl Block

pub fn calc_tx_witness_hashes(&self) -> Vec<Byte32>

Calls BlockReader.calc_tx_witness_hashes() for self.as_reader().

impl Block

pub fn serialized_size_without_uncle_proposals(&self) -> usize

Calls Block::serialized_size_without_uncle_proposals(..).

impl Block

pub fn as_uncle(&self) -> UncleBlock

Converts self to an uncle block.

pub fn reset_header(self) -> Block

Recalculates all hashes and merkle roots in the header.

pub fn extra_field(&self, index: usize) -> Option<Bytes>

Gets the i-th extra field if it exists; i started from 0.

pub fn extension(&self) -> Option<Bytes>

Gets the extension field if it existed.

Panics

Panics if the first extra field exists but not a valid Bytes.

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() -> Self

Returns the “default value” for a type.

impl Display for Block

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

Formats the value using the given formatter.

impl Entity for Block

type Builder = BlockBuilder

const NAME: &'static str = "Block"

fn new_unchecked(data: Bytes) -> Self

fn as_bytes(&self) -> Bytes

fn as_slice(&self) -> &[u8]

fn from_slice(slice: &[u8]) -> VerificationResult<Self>

fn from_compatible_slice(slice: &[u8]) -> VerificationResult<Self>

fn new_builder() -> Self::Builder

fn as_builder(self) -> Self::Builder

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 LowerHex for Block

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

Formats the value using the given formatter.

impl PartialEq<Block> for Block

fn eq(&self, other: &Self) -> 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.
