Struct SyncApplier 

Source 
pub struct SyncApplier<T, F>
where
    T: Clone + Send + Sync + 'static,
    F: Fn(T) -> Result<(), String> + Send + Sync + 'static,
{ /* private fields */ }
Expand description

Convenience wrapper for synchronous appliers. Most appliers just set an atomic or reconfigure a rate limiter and have no genuine async work to do — this wrapper lifts a plain Fn(T) -> Result<(), String> into a ControlApplier<T>.
