Trait LaunchExEx

pub trait LaunchExEx<Node: FullNodeComponents>: Send {
    // Required method
    fn launch(
        self,
        ctx: ExExContext<Node>,
    ) -> impl Future<Output = Result<impl Future<Output = Result<()>> + Send>> + Send;
}

A trait for launching an ExEx.

Required Methods

fn launch( self, ctx: ExExContext<Node>, ) -> impl Future<Output = Result<impl Future<Output = Result<()>> + Send>> + Send

Launches the ExEx.

The ExEx should be able to run independently and emit events on the channels provided in the [ExExContext].

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.

Implementors

impl<Node, F, Fut, E> LaunchExEx<Node> for F

where Node: FullNodeComponents, F: FnOnce(ExExContext<Node>) -> Fut + Send, Fut: Future<Output = Result<E>> + Send, E: Future<Output = Result<()>> + Send,

Implements LaunchExEx for any closure that takes an [ExExContext] and returns a future resolving to an ExEx.
