Trait Launcher

pub trait Launcher<C, Ext>
where
    C: ChainSpecParser,
    Ext: Args + Debug,
{
    // Required method
    fn entrypoint(
        self,
        builder: WithLaunchContext<NodeBuilder<Arc<DatabaseEnv>, C::ChainSpec>>,
        builder_args: Ext,
    ) -> impl Future<Output = Result<()>>;
}

A trait for launching a reth node with custom configuration strategies.

This trait allows defining node configuration through various object types rather than just functions. By implementing this trait on your own structures, you can:

• Create flexible configurations that connect necessary components without creating separate closures
• Take advantage of decomposition to break complex configurations into a series of methods
• Encapsulate configuration logic in dedicated types with their own state and behavior
• Reuse configuration patterns across different parts of your application

Required Methods

fn entrypoint( self, builder: WithLaunchContext<NodeBuilder<Arc<DatabaseEnv>, C::ChainSpec>>, builder_args: Ext, ) -> impl Future<Output = Result<()>>

Entry point for launching a node with custom configuration.

Consumes self to use pre-configured state, takes a builder and arguments, and returns an async future.

Arguments

• builder - Node builder with launch context
• builder_args - Extension arguments for configuration

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.
