pub struct TransactionsRequest { /* fields omitted */ }

Request for transactions by hash.

Processing

Requested transactions are sent to the recipient.

Generation

This message can be sent during Propose, Prevote and Precommit handling.

Methods

impl TransactionsRequest

pub fn new(     from: &PublicKey,     to: &PublicKey,     txs: &[Hash],     secret_key: &SecretKey ) -> TransactionsRequest

Creates message and signs it.

pub fn new_with_signature(     from: &PublicKey,     to: &PublicKey,     txs: &[Hash],     signature: &Signature ) -> TransactionsRequest
