1//! Service trait for ma endpoint protocol handlers.
2//!
3//! A `Service` is analogous to an entry in `/etc/services`: a named protocol
4//! on a ma endpoint. Register services on an `MaEndpoint` to handle incoming
5//! connections on their protocol.
6
7/// Trait that all ma services must implement.
8///
9/// Each service declares its protocol identifier and provides a handler for
10/// incoming connections. Built-in services ship with ma-core; applications
11/// add custom services via this trait.
12///
13/// # Examples
14///
15/// ```
16/// use ma_core::Service;
17///
18/// struct MyService;
19///
20/// impl Service for MyService {
21///     fn protocol(&self) -> &[u8] { b"/ma/my-service/0.0.1" }
22/// }
23/// ```
24pub trait Service: Send + Sync {
25    /// The protocol identifier for this service.
26    fn protocol(&self) -> &[u8];
27}
