Trait genserver::GenServer

pub trait GenServer {
    type Message;
    type Response;
    type Registry;
    type CallResponse<'a>: Future<Output = Self::Response>
   where
        Self: 'a;
    type CastResponse<'a>: Future<Output = ()>
   where
        Self: 'a;

    fn new(registry: Self::Registry) -> Self;
    fn handle_call(&mut self, message: Self::Message) -> Self::CallResponse<'_>;
    fn handle_cast(&mut self, message: Self::Message) -> Self::CastResponse<'_>;

    fn channel_queue_size() -> usize { ... }
}

The GenServer trait lets you generate a server, by implementing the trait.

Required Associated Types

type Message

Specifies the type of messages this server can receive.

type Response

Specifies the response from calls.

type Registry

Specifies the name of the registry type created with make_registry.

type CallResponse<'a>: Future<Output = Self::Response>
where
    Self: 'a

Specifies the call response type, which must implement std::future::Future.

type CastResponse<'a>: Future<Output = ()>
where
    Self: 'a

Specifies the call response type, which must implement std::future::Future and return ().

Required Methods

fn new(registry: Self::Registry) -> Self

Creates a new server, and receives a copy of the current registry.

You should never need to call this method yourself, as it’s called for you by the registry.

fn handle_call(&mut self, message: Self::Message) -> Self::CallResponse<'_>

This function will be called whenever this server receives a call.

fn handle_cast(&mut self, message: Self::Message) -> Self::CastResponse<'_>

This function will be called whenever this server receives a cast.

Provided Methods

fn channel_queue_size() -> usize

Reimplement this method to change the channel queue size for your server. Defaults to 1000 messages.
