Struct MasternodeYesNoVoteDriveQuery 

pub struct MasternodeYesNoVoteDriveQuery {
    pub pro_tx_hash: Identifier,
    pub vote_poll_id: Identifier,
}

The query for a masternode’s answer on a yes/no vote poll: the item keyed by the poll’s id under the masternode’s tree of yes/no votes. The item is removed when the poll finishes.

Fields

pro_tx_hash: Identifier

The masternode’s pro tx hash

vote_poll_id: Identifier

The id of the poll, as YesNoVotePoll::unique_id derives it

Implementations

impl MasternodeYesNoVoteDriveQuery

pub fn construct_path_query(&self) -> PathQuery

The path query: the poll’s key under the masternode’s tree of yes/no votes.

pub fn execute_with_proof( &self, drive: &Drive, transaction: TransactionArg<'_, '_>, drive_operations: &mut Vec<LowLevelDriveOperation>, platform_version: &PlatformVersion, ) -> Result<Vec<u8>, Error>

Proves the masternode’s answer, or its absence, by the method version the platform version selects (vote.yes_no.prove_identity_yes_no_vote, not active before protocol version 15).

Parameters

• drive: the Drive to read.
• transaction: the transaction to read in.
• drive_operations: collects the read’s operations.
• platform_version: the platform version.

Returns

The proof.

pub fn execute_no_proof( &self, drive: &Drive, transaction: TransactionArg<'_, '_>, drive_operations: &mut Vec<LowLevelDriveOperation>, platform_version: &PlatformVersion, ) -> Result<Option<MasternodeYesNoVote>, Error>

Reads the masternode’s answer, or None when it has not voted on the poll (or the poll finished and its votes were removed), through Drive::fetch_identity_yes_no_vote.

Parameters

• drive: the Drive to read.
• transaction: the transaction to read in.
• drive_operations: collects the read’s operations.
• platform_version: the platform version.

Returns

The masternode’s answer, if any.

impl MasternodeYesNoVoteDriveQuery

pub fn verify_identity_yes_no_vote( &self, proof: &[u8], verify_subset_of_proof: bool, platform_version: &PlatformVersion, ) -> Result<(RootHash, Option<MasternodeYesNoVote>), Error>

Verifies a proof of a masternode’s answer on a yes/no poll, by the poll’s id, by the method version the platform version selects (verify.voting.verify_identity_yes_no_vote, not active before protocol version 15).

Parameters

• proof: the proof.
• verify_subset_of_proof: whether the proof may hold more than this answer.
• platform_version: the platform version.

Returns

The root hash and the proved answer, None when the masternode has not voted on the poll (or the poll finished and its votes were removed).
