Struct exonum::blockchain::ServiceContext

pub struct ServiceContext<'a, 'b> { /* fields omitted */ }

The current node state on which the blockchain is running, or in other words execution context.

Methods

impl<'a, 'b> ServiceContext<'a, 'b>

fn validator_state(&self) -> &Option<ValidatorState>

If the current node is validator returns its state. For other nodes return None.

fn snapshot(&self) -> &'b Snapshot

Returns the current database snapshot.

fn height(&self) -> u64

Returns the current blockchain height. This height is 'height of last committed block` + 1.

fn round(&self) -> u32

Returns the current node round.

fn validators(&self) -> &[ValidatorKeys]

Returns the current list of validators.

fn public_key(&self) -> &PublicKey

Returns current node's public key.

fn secret_key(&self) -> &SecretKey

Returns current node's secret key.

fn actual_consensus_config(&self) -> &ConsensusConfig

Returns the actual blockchain global configuration.

fn actual_service_config(&self, service: &Service) -> &Value

Returns service specific global variables as json value.

fn add_transaction(&mut self, tx: Box<Transaction>)

Adds transaction to the queue. After the services handle commit event these transactions will be broadcast by node.
