Struct finality_grandpa::HistoricalVotes

pub struct HistoricalVotes<H, N, S, Id> { /* private fields */ }

Historical votes seen in a round.

Implementations

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

pub fn new() -> Self

Create a new HistoricalVotes.

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.

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.

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

Return the messages seen so far.

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

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

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

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

pub fn set_prevoted_idx(&mut self)

Set the number of messages seen before prevoting.

pub fn set_precommitted_idx(&mut self)

Set the number of messages seen before precommiting.

    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<H: Default, N: Default, S: Default, Id: Default> Default for HistoricalVotes<H, N, S, Id>

fn default() -> HistoricalVotes<H, N, S, Id>

Returns the “default value” for a type.

impl<H, N, S, Id> Encode for HistoricalVotes<H, N, S, Id>where
    Vec<SignedMessage<H, N, S, Id>>: Encode,

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,

impl<H: PartialEq, N: PartialEq, S: PartialEq, Id: PartialEq> PartialEq<HistoricalVotes<H, N, S, Id>> for HistoricalVotes<H, N, S, Id>

fn eq(&self, other: &HistoricalVotes<H, N, S, Id>) -> 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.
