Struct VoteTracker 

pub struct VoteTracker<S: Scheme, D: Digest> { /* private fields */ }

Tracks notarize/nullify/finalize votes for a view.

Each vote type is stored in its own AttributableMap so a validator can only contribute one vote per phase. The tracker is reused across rounds/views to keep allocations stable.

Implementations

impl<S: Scheme, D: Digest> VoteTracker<S, D>

pub fn new(participants: usize) -> Self

Creates a tracker sized for participants validators.

pub fn insert_notarize(&mut self, vote: Notarize<S, D>) -> bool

Inserts a notarize vote if the signer has not already voted.

pub fn insert_nullify(&mut self, vote: Nullify<S>) -> bool

Inserts a nullify vote if the signer has not already voted.

pub fn insert_finalize(&mut self, vote: Finalize<S, D>) -> bool

Inserts a finalize vote if the signer has not already voted.

pub fn notarize(&self, signer: Participant) -> Option<&Notarize<S, D>>

Returns the notarize vote for signer, if present.

pub fn nullify(&self, signer: Participant) -> Option<&Nullify<S>>

Returns the nullify vote for signer, if present.

pub fn finalize(&self, signer: Participant) -> Option<&Finalize<S, D>>

Returns the finalize vote for signer, if present.

pub fn iter_notarizes(&self) -> impl Iterator<Item = &Notarize<S, D>>

Iterates over notarize votes in signer order.

pub fn iter_nullifies(&self) -> impl Iterator<Item = &Nullify<S>>

Iterates over nullify votes in signer order.

pub fn iter_finalizes(&self) -> impl Iterator<Item = &Finalize<S, D>>

Iterates over finalize votes in signer order.

pub fn len_notarizes(&self) -> u32

Returns how many notarize votes have been recorded.

pub fn len_nullifies(&self) -> u32

Returns how many nullify votes have been recorded.

pub fn len_finalizes(&self) -> u32

Returns how many finalize votes have been recorded.

pub fn has_notarize(&self, signer: Participant) -> bool

Returns true if the given signer has a notarize vote recorded.

pub fn has_nullify(&self, signer: Participant) -> bool

Returns true if a nullify vote has been recorded for signer.

pub fn has_finalize(&self, signer: Participant) -> bool

Returns true if a finalize vote has been recorded for signer.

pub fn clear_notarizes(&mut self)

Clears all notarize votes but keeps the allocations for reuse.

pub fn clear_finalizes(&mut self)

Clears all finalize votes but keeps the allocations for reuse.
