Implementations

source

impl Justifications

source

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

Return an iterator over the justifications.

source

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

source

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

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

source

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.
