Struct exonum::messages::Precommit

#[non_exhaustive]pub struct Precommit {
    pub validator: ValidatorId,
    pub epoch: Height,
    pub round: Round,
    pub propose_hash: Hash,
    pub block_hash: Hash,
    pub time: DateTime<Utc>,
}

Pre-commit for a block, essentially meaning that a validator node endorses the block. The consensus algorithm ensures that once a Byzantine majority of validators has endorsed a block, no other block at the same height may be endorsed at any point in the future. Thus, such a block can be considered committed.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

validator: ValidatorId

ID of the validator endorsing the block.

epoch: Height

The height to which the message is related.

round: Round

The round to which the message is related.

propose_hash: Hash

Hash of the block proposal. Note that the proposal format is not defined by the core.

block_hash: Hash

Hash of the new block.

time: DateTime<Utc>

Local time of the validator node when the Precommit was created.
