fn clone(&self) -> ProposalHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProposalHeader

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

Formats the value using the given formatter.

impl Decode for ProposalHeader

fn decode<I: Input>(input: &mut I) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

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.

impl<'de> Deserialize<'de> for ProposalHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for ProposalHeader

fn size_hint(&self) -> usize

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

fn encode_to<T: Output + ?Sized>(&self, dest: &mut T)

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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 From<[u8; 40]> for ProposalHeader

fn from(bytes: [u8; 40]) -> Self

Converts to this type from the input type.

impl From<ProposalHeader> for [u8; 40]

fn from(header: ProposalHeader) -> Self

impl Hash for ProposalHeader

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,

impl Ord for ProposalHeader

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

This method returns an Ordering between self and other.
