Node fast-sync configuration.

Fields

trusted_hash: Option<BlockHash>

Hash used as a trust anchor when joining, if any.

sync_handling: SyncHandling

Which historical sync option? Genesis: sync all the way back to genesis Ttl: sync the necessary number of historical blocks to satisfy TTL requirement. NoSync: don’t attempt to get any historical records; i.e. go forward only.

idle_tolerance: TimeDiff

Idle time after which the syncing process is considered stalled.

max_attempts: usize

When the syncing process is considered stalled, it’ll be retried up to max_attempts times.

control_logic_default_delay: TimeDiff

Default delay for the control events that have no dedicated delay requirements.

force_resync: bool

Flag which forces the node to resync all of the blocks.

shutdown_for_upgrade_timeout: TimeDiff

Shutdown for upgrade state timeout, after which the node will upgrade regardless whether all the conditions are satisfied.

upgrade_timeout: TimeDiff

Maximum time a node will wait for an upgrade to commit.

prevent_validator_shutdown: bool

If true, prevents a node from shutting down if it is supposed to be a validator in the era.

Trait Implementations

impl Clone for NodeConfig

fn clone(&self) -> NodeConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for NodeConfig

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

fn estimate_detailed_heap_size(&self) -> MemUsageNode

Create a tree of memory estimations.

impl Debug for NodeConfig

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

Formats the value using the given formatter.

impl Default for NodeConfig

fn default() -> NodeConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NodeConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for NodeConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
