Struct sp_runtime::Justifications

pub struct Justifications(/* private fields */);

Collection of justifications for a given block, multiple justifications may be provided by different consensus engines for the same block.

Implementations

impl Justifications

pub fn iter(&self) -> impl Iterator<Item = &Justification>

Return an iterator over the justifications.

pub fn append(&mut self, justification: Justification) -> bool

Append a justification. Returns false if a justification with the same ConsensusEngineId already exists, in which case the justification is not inserted.

pub fn get(&self, engine_id: ConsensusEngineId) -> Option<&EncodedJustification>

Return the encoded justification for the given consensus engine, if it exists.

pub fn remove(&mut self, engine_id: ConsensusEngineId)

Remove the encoded justification for the given consensus engine, if it exists.

pub fn into_justification( self, engine_id: ConsensusEngineId ) -> Option<EncodedJustification>

Return a copy of the encoded justification for the given consensus engine, if it exists.

Trait Implementations

impl Clone for Justifications

fn clone(&self) -> Justifications

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Justifications

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

Formats the value using the given formatter.

impl Decode for Justifications

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<'de> Deserialize<'de> for Justifications

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Justifications

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>

Convert self to an owned vector.

fn using_encoded<R, F: FnOnce(&[u8]) -> R>(&self, f: F) -> 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; 4], Vec<u8>)> for Justifications

fn from(justification: Justification) -> Self

Converts to this type from the input type.

impl IntoIterator for Justifications

type Item = ([u8; 4], Vec<u8>)

The type of the elements being iterated over.

type IntoIter = IntoIter<<Justifications as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Justifications

fn eq(&self, other: &Justifications) -> 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 Serialize for Justifications

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
