Trait representing generic output from an election method

Required methods

fn meta(&self) -> &Metadata

Reference to the election metadata

fn deterministic(&self) -> bool

Specify whether the election was deterministic

In other words, returns false whenever PRNG was used to settle the election.

In case of ranked pairs method, there is a chance for false negatives, i.e. elections deemed not deterministic while there were.

In case of Meek and Warren methods, determinisms may also depend on the numerical issues due to an use of fixed point arithmetic.

ⓘImportant traits for CandidateIterator<'a>
fn elected(&self) -> CandidateIterator

Return iterator of IDs of elected candidates

fn candidate_count(&self) -> usize

Provided methods

fn elected_count(&self) -> usize

ⓘImportant traits for NamesIterator<'a>
fn elected_names(&self) -> NamesIterator

Return iterator of elected candidate names

When there is no name for some candidate (or no names at all), placeholder names featuring 1-based indices of candidates will be generated.

fn winner(&self) -> Option<u32>

Return a single winner ID, if there is one, that is either the election scheme is single winner one or there is one seat in multi-winner election

fn winner_name(&self) -> Option<String>

fn withdrawn_count(&self) -> usize

ⓘImportant traits for NamesIterator<'a>
fn withdrawn_names(&self) -> NamesIterator

Return iterator of names of withdrawn candidates
