pub fn set_limit_warning_handler(
handler: Box<dyn Fn(&LimitWarning) + Send + Sync>,
)Expand description
Install a process-global sink that is invoked on the same edge-triggered,
hysteresis-gated boundary as the tracing::warn! whenever a tracked limit
crosses WARN_FILL_PERCENT. The sidecar uses this to forward limit warnings
to the host as structured events (the onLimitWarning hook). The handler must
be cheap and non-blocking; it runs on the producer’s thread.
