Struct exonum::messages::PeersRequest

pub struct PeersRequest { /* fields omitted */ }

Request connected peers from a node.

Validation

Request is considered valid if the sender of the message on the network level corresponds to the from field.

Processing

Peer Connect messages are sent to the recipient.

Generation

PeersRequest message is sent regularly with the timeout controlled by blockchain::ConsensusConfig::peers_timeout.

pub fn new(
    from: &PublicKey,
    to: &PublicKey,
    secret_key: &SecretKey
) -> PeersRequest

Creates message and signs it.

pub fn new_with_signature(
    from: &PublicKey,
    to: &PublicKey,
    signature: &Signature
) -> PeersRequest
