Struct exonum_cli::NodeBuilder

pub struct NodeBuilder { /* fields omitted */ }

Rust-specific node builder used for constructing a node with a list of provided services.

Methods

impl NodeBuilder

pub fn new() -> Self

Creates a new builder.

pub fn development_node() -> Result<Self>

Creates a single-node development network with default settings. The node stores its data in a temporary directory, which is automatically removed when the node is stopped.

Return value

Returns an error if the temporary directory cannot be created.

pub fn with(self, spec: impl Deploy) -> Self

Adds a deploy spec to this builder. The spec may contain artifacts and service instances to deploy at the blockchain start.

pub fn with_external_runtime(self, runtime: impl WellKnownRuntime) -> Self

Adds a new Runtime to the list of available runtimes.

Note that you don't have to add the Rust runtime, since it is included by default.

pub async fn run(__arg0: Self) -> Result<()>

Configures the node using parameters provided by user from stdin and then runs it.
