Trait LaunchNode

pub trait LaunchNode<Target> {
    type Node;

    // Required method
    fn launch_node(
        self,
        target: Target,
    ) -> impl Future<Output = Result<Self::Node, Report>>;
}

A general purpose trait that launches a new node of any kind.

Acts as a node factory that targets a certain node configuration and returns a handle to the node.

This is essentially the launch logic for a node.

Required Associated Types

type Node

The node type that is created.

Required Methods

fn launch_node( self, target: Target, ) -> impl Future<Output = Result<Self::Node, Report>>

Create and return a new node asynchronously.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
