Expand description

Historical votes seen in a round.

Implementations§

Source§

impl<H, N, S, Id> HistoricalVotes<H, N, S, Id>

Source

pub fn new() -> Self

Create a new HistoricalVotes.

Source

pub fn new_with( seen: Vec<SignedMessage<H, N, S, Id>>, prevote_idx: Option<u64>, precommit_idx: Option<u64>, ) -> Self

Create a new HistoricalVotes initialized from the parameters.

Source

pub fn push_vote(&mut self, msg: SignedMessage<H, N, S, Id>)

Push a vote into the list. The value of self before this call is considered to be a prefix of the value post-call.

Source

pub fn seen(&self) -> &[SignedMessage<H, N, S, Id>]

Return the messages seen so far.

Source

pub fn prevote_idx(&self) -> Option<u64>

Return the number of messages seen before prevoting. None in case we didn’t prevote yet.

Source

pub fn precommit_idx(&self) -> Option<u64>

Return the number of messages seen before precommiting. None in case we didn’t precommit yet.

Source

pub fn set_prevoted_idx(&mut self)

Set the number of messages seen before prevoting.

Source

pub fn set_precommitted_idx(&mut self)

Set the number of messages seen before precommiting.
