statesync configuration options

Fields

enable: bool

State sync rapidly bootstraps a new node by discovering, fetching, and restoring a state machine snapshot from peers instead of fetching and replaying historical blocks. Requires some peers in the network to take and serve state machine snapshots. State sync is not attempted if the node has any local state (LastBlockHeight > 0). The node will have a truncated block history, starting from the height of the snapshot.

rpc_servers: Vec<String>

RPC servers (comma-separated) for light client verification of the synced state machine and retrieval of state data for node bootstrapping. Also needs a trusted height and corresponding header hash obtained from a trusted source, and a period during which validators can be trusted.

For Cosmos SDK-based chains, trust-period should usually be about 2/3 of the unbonding time (~2 weeks) during which they can be financially punished (slashed) for misbehavior.

trust_height: u64

Trust height. See rpc_servers above.

trust_hash: String

Trust hash. See rpc_servers above.

trust_period: String

Trust period. See rpc_servers above.

discovery_time: Timeout

Time to spend discovering snapshots before initiating a restore.

temp_dir: String

Temporary directory for state sync snapshot chunks, defaults to the OS tempdir (typically /tmp). Will create a new, randomly named directory within, and remove it when done.

Trait Implementations

impl Clone for StatesyncConfig

fn clone(&self) -> StatesyncConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatesyncConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StatesyncConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StatesyncConfig

fn eq(&self, other: &StatesyncConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StatesyncConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
