-Every worker receives a [Request<String\>](https://docs.rs/http/0.2.8/http/request/struct.Request.html) struct and returns a [Response<String\>](https://docs.rs/http/0.2.8/http/response/struct.Response.html).

These structs come from the widely known [`http` crate](https://docs.rs/http/) and the `Content` struct is defined in our rust kit. It allows you returning different types. Finally, the `handler` macro connects your worker with `wws`.
