Expand description

Configuration parameters for the chain worker and its owning WorkerState.

Fields§

§nickname: String

A name used for logging.

§key_pair: Option<Arc<ValidatorSecretKey>>

The signature key pair of the validator. The key may be missing for replicas without voting rights (possibly with a partial view of chains).

§allow_inactive_chains: bool

Whether inactive chains are allowed in storage.

§allow_messages_from_deprecated_epochs: bool

Whether new messages from deprecated epochs are allowed.

§long_lived_services: bool

Whether the user application services should be long-lived.

§block_time_grace_period: Duration

Blocks with a timestamp this far in the future will still be accepted, but the validator will wait until that timestamp before voting.

§ttl: Option<Duration>

Idle chain workers free their memory after this duration without requests. None means no expiry (handle lives forever).

§sender_chain_ttl: Option<Duration>

TTL for sender chains. None means no expiry.

§chain_info_max_received_log_entries: usize

The size to truncate receive log entries in chain info responses.

§block_cache_size: usize

Maximum number of entries in the block cache.

§execution_state_cache_size: usize

Maximum number of entries in the execution state cache.
