Function sp_npos_elections::pjr::pjr_check_core

pub fn pjr_check_core<AccountId: IdentifierT>(
    candidates: &[CandidatePtr<AccountId>],
    voters: &[Voter<AccountId>],
    t: ExtendedBalance
) -> Result<(), AccountId>

The internal implementation of the PJR check after having the data converted.

pjr_check or t_pjr_check are typically easier to work with.

This function returns an AccountId in the Err case. This is the counter_example: the ID of the unelected candidate with the highest prescore, such that pre_score(counter_example) >= t.
