Trait EventSource 

pub trait EventSource: Send + 'static {
    // Required method
    fn recv(&mut self) -> impl Future<Output = Option<String>> + Send;
}

Contract for event input adapters.

Each source reads events from a specific input (stdin, HTTP, NATS) and yields raw strings (typically JSON lines). Sources are used as concrete types (not dyn), so async fn is valid without object-safety concerns.

Required Methods

fn recv(&mut self) -> impl Future<Output = Option<String>> + Send

Receive the next event as a raw string. Returns None when the source is exhausted or shutting down.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
