Expand description

Trait that defines app/service’s request handler and router See rustwasm-service-template for a more complete example

 use service_logging::{Severity::Verbose,log,Logger};
 use wasm_service::{Context,Handler,HandlerReturn,Request};
 use async_trait::async_trait;
 struct MyHandler {}
 #[async_trait(?Send)]
 impl Handler for MyHandler {
     /// Process incoming Request
     async fn handle(&self, req: &Request, ctx: &mut Context) -> Result<(), HandlerReturn> {
         // log all incoming requests
         log!(ctx, Verbose, method: req.method(), url: req.url());
         match (req.method(), req.url().path()) {
             (GET, "/hello") => {
                 ctx.response().content_type("text/plain; charset=UTF-8").unwrap()
                               .text("Hello world!");
             }
             _ => {
                 ctx.response().status(404).text("Not Found");
             }
         }
         Ok(())
     }
 }
