Struct holochain::prelude::dependencies::kitsune_p2p_types::dependencies::ghost_actor::dependencies::tracing::subscriber::NoSubscriber
pub struct NoSubscriber(/* private fields */);
Expand description
A no-op Subscriber
.
NoSubscriber
implements the Subscriber
trait by never being enabled,
never being interested in any callsite, and dropping all spans and events.
