wasmCloud Core Actor Interface

All actors must respond to the core HealthCheckRequest message with either an Err or a HealthCheckResponse. The following is an example of what an actor looks like that only responds to the health check message:

```rust use wapc_guest::HandlerResult; use actorcore::{HealthCheckRequest, HealthCheckResponse, Handlers};

#[nomangle] pub fn wapcinit() { Handlers::registerhealthrequest(health); }

fn health(_msg: HealthCheckRequest) -> HandlerResult { Ok(HealthCheckResponse::healthy()) } ```
