}

An implementor of a Maelstrom workload.

Required Methods

fn init<'life0, 'life1, 'async_trait>( args: &'life0 Args, handle: &'life1 Handle, ) -> Pin<Box<dyn Future<Output = Result<Self, MaelstromError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Construct this service.

Maelstrom services are available via the Handle.

fn eval<'life0, 'async_trait>( &'life0 self, handle: Handle, src: NodeId, req: Body, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Respond to a single request.

Implementations must either panic or respond by calling Handle::send_res exactly once.

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.
