Struct exonum_node::NodeBuilder

pub struct NodeBuilder { /* fields omitted */ }

Builder for Node.

Methods

impl NodeBuilder

pub fn new(
    database: impl Into<Arc<dyn Database>>,
    node_config: NodeConfig,
    node_keys: Keys
) -> Self

Instantiates a builder.

pub fn with_genesis_config(self, genesis_config: GenesisConfig) -> Self

Adds a genesis config to use if the blockchain is not initialized yet.

pub fn with_runtime<T>(self, runtime: T) -> Self where
    T: Into<RuntimeInstance>, 

Adds a runtime to the blockchain.

pub fn with_runtime_fn<T, F>(self, runtime_fn: F) -> Self where
    T: Into<RuntimeInstance>,
    F: FnOnce(&NodeChannel) -> T, 

Adds a runtime which depends on a NodeChannel (e.g., to update HTTP API of the node).

pub fn with_config_manager<T: ConfigManager + 'static>(self, manager: T) -> Self

Adds the configuration manager.

pub fn with_block_proposer<T: ProposeBlock + 'static>(self, proposer: T) -> Self

Sets custom Propose creation logic for the node.

Stability and safety

Using a custom proposer CAN LEAD TO CONSENSUS FAILURE. See the proposer module docs for more details.

pub fn with_plugin<T: NodePlugin + 'static>(self, plugin: T) -> Self

Adds a plugin.

pub fn disable_signals(self) -> Self

Switches off default signal handling for the node. This is useful to implement more complex signal handling, or one that differs from the default.

If you use custom signal handlers, the node may be shut down gracefully using ShutdownHandle.

pub fn build(self) -> Node

Converts this builder into a Node.

Trait Implementations

impl Debug for NodeBuilder

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

Formats the value using the given formatter.
