Trait uni_components::service::Service

pub trait Service {
    type In: 'static + DeserializeOwned + Serialize;
    type Out: 'static + DeserializeOwned + Serialize;
    fn path(&self) -> &str;
    fn kind(&self) -> Kind;
    fn from_response(
        &self
    ) -> fn(response: Response) -> Result<Self::Out, Response>;

    fn exec(
        &self, 
        parameter: &Self::In, 
        slot: &dyn Slot<Result<Self::Out, Response>>
    ) -> Result<(), CallError> { ... }
}

Represents server side handler.

It's a good idea to use define_service! instead of trying to implement the trait by yourself.
