Implementations

impl BlockHeader

pub fn hash(&self) -> Result<H256Le, Error>

Returns the hash of the block header using Bitcoin’s double sha256

pub fn ensure_version(&self) -> Result<(), Error>

pub fn update_hash(&mut self) -> Result<H256Le, Error>

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 Decode for BlockHeader

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for BlockHeader

fn default() -> BlockHeader

Returns the “default value” for a type.

impl Encode for BlockHeader

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl MaxEncodedLen for BlockHeader

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq<BlockHeader> 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 TryFormat for BlockHeader

fn try_format<W: Writer>(&self, w: &mut W) -> Result<(), Error>

impl TypeInfo for BlockHeader

type Identity = BlockHeader

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Copy for BlockHeader

impl EncodeLike<BlockHeader> for BlockHeader

impl Eq for BlockHeader

impl StructuralEq for BlockHeader

impl StructuralPartialEq for BlockHeader
