Struct TracingBus 

pub struct TracingBus { /* private fields */ }

Central hub that receives RosaceTrace events and dispatches to all registered TraceSubscriber implementations.

Access via the TRACING_BUS global singleton. The bus is zero-cost in production — all trace!() call sites are stripped by #[cfg(debug_assertions)].

Implementations

impl TracingBus

pub const fn new() -> Self

Creates a new bus with no subscribers.

pub fn add_subscriber(&self, subscriber: Arc<dyn TraceSubscriber + Send + Sync>)

Registers a subscriber to receive all future trace events.

pub fn clear_subscribers(&self)

Removes all registered subscribers.

pub fn emit(&self, event: RosaceTrace)

Emits a trace event to all registered subscribers.

The subscriber list lock is released before calling any subscriber so that subscribers can safely call add_subscriber without deadlocking.

Trait Implementations

impl Default for TracingBus

fn default() -> Self

Returns the “default value” for a type.
