Macro trace 

macro_rules! trace {
    ($event:expr) => { ... };
}

Emits a RosaceTrace event — zero cost in production.

In debug builds, forwards the event to TRACING_BUS. In release builds, the entire call is compiled away with no overhead.

Example

use rosace_trace::{trace, event::{RosaceTrace, ComponentId}, location};

trace!(RosaceTrace::ComponentUnmount {
    id: ComponentId(1),
    name: "MyComponent",
});
