Struct exonum::blockchain::config::StoredConfiguration

pub struct StoredConfiguration {
    pub previous_cfg_hash: Hash,
    pub actual_from: Height,
    pub validator_keys: Vec<ValidatorKeys>,
    pub consensus: ConsensusConfig,
    pub services: BTreeMap<String, Value>,
}

Exonum blockchain global configuration. This configuration must be same for any exonum node in the certain network on given height.

Fields

previous_cfg_hash: Hash

Link to the previous configuration. For configuration in the genesis block hash is just an array of zeros.

actual_from: Height

The height, starting from which this configuration becomes actual.

validator_keys: Vec<ValidatorKeys>

List of validator's consensus and service public keys.

consensus: ConsensusConfig

Consensus algorithm parameters.

services: BTreeMap<String, Value>

Services specific variables. Keys are service_name from Service trait and values are the serialized json.

Methods

impl StoredConfiguration

fn try_serialize(&self) -> Result<Vec<u8>, JsonError>

Tries to serialize given configuration into the utf8 encoded json.

fn try_deserialize(serialized: &[u8]) -> Result<StoredConfiguration, JsonError>

Tries to deserialize StorageConfiguration from the given utf8 encoded json.

Trait Implementations

impl Clone for StoredConfiguration

fn clone(&self) -> StoredConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StoredConfiguration

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for StoredConfiguration

fn eq(&self, __arg_0: &StoredConfiguration) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &StoredConfiguration) -> bool

This method tests for !=.

impl StorageValue for StoredConfiguration

fn into_bytes(self) -> Vec<u8>
