Trait EventStream 

pub trait EventStream: Send {
    // Required method
    fn try_next(&mut self) -> Option<Event>;
}

Non-blocking event stream from a scryer subscription.

In production this wraps an async stream from the scryer client (R093-F1+F2). In tests a channel-backed implementation provides deterministic event feeds. Subscriptions are closed by dropping the Box<dyn EventStream>.

Required Methods

fn try_next(&mut self) -> Option<Event>

Return the next available event without blocking. Returns None if no event is currently available.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
