Struct exonum::messages::Status
[−]
[src]
pub struct Status { /* fields omitted */ }
Current node status.
Validation
The message is ignored if its signature is incorrect or its height
is
lower than a node's height.
Processing
If the message's height
number is bigger than a node's one, then
BlockRequest
with current node's height is sent in reply.
Generation
Status
message is broadcast regularly with the timeout controlled by
blockchain::ConsensusConfig::status_timeout
. Also, it is broadcast
after accepting a new block.
Methods
impl Status
[src]
pub fn new(
from: &PublicKey,
height: Height,
last_hash: &Hash,
secret_key: &SecretKey
) -> Status
[src]
from: &PublicKey,
height: Height,
last_hash: &Hash,
