Trait RuntimeMarker

pub trait RuntimeMarker: Sealed { }

Marker trait for runtime types.

This trait is used to mark types that represent different async runtimes (such as Tokio or async-std) or the absence of an async runtime.

Examples

use cel_cxx::marker::RuntimeMarker;

// The unit type represents no async runtime
fn sync_example<R: RuntimeMarker>() {
    // This works with any runtime marker
}
