Struct Node 

pub struct Node<T: NodeImpl> { /* private fields */ }

Wrapper that manages the lifecycle of a NodeImpl.

This provides:

• State management
• Lifecycle orchestration
• Error handling
• Health monitoring

Implementations

impl<T: NodeImpl> Node<T>

pub async fn from_config(config: T::Config) -> Result<Self>

Create a new node from a configuration.

This calls NodeImpl::init() and wraps the result in a Node.

Errors

Returns an error if initialization fails.

pub async fn start(&self, ctx: Context) -> Result<()>

Start the node with the given context.

This orchestrates the full lifecycle:

1. Transition to Running state
2. Call run()
3. Call shutdown() on completion or error
4. Transition to final state

Errors

Returns an error if the node fails during execution.

pub async fn shutdown(&self) -> Result<()>

Gracefully shutdown the node.

This calls shutdown() and transitions to Stopped state.

pub async fn state(&self) -> NodeState

Get the current state of the node.

pub async fn health_check(&self) -> HealthStatus

Perform a health check on the node.

pub async fn is_healthy(&self) -> bool

Check if the node is healthy.

Trait Implementations

impl<T: Clone + NodeImpl> Clone for Node<T>

fn clone(&self) -> Node<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
