Crate tracelimit

Implementations of [tracing] macros that are rate limited.

These are useful when an untrusted entity can arbitrarily trigger an event to be logged. In that case, rate limiting the events can prevent other important events from being lost.

Note that there currently are no macros for rate limiting debug or trace level events. This is due to an implementation limitation–the macros in this crate check the rate limit before evaluating whether the event should be logged, and so this would add an extra check to every debug/trace event. This could be fixed by using some of the hidden but pub machinery of the tracing crate, which is probably not worth it for now.

Macros

• error_ratelimited
  As [tracing::error!], but rate limited.
• info_ratelimited
  As [tracing::info!], but rate limited.
• warn_ratelimited
  As [tracing::warn!], but rate limited.

Functions

• disable_rate_limiting
  Disables or reenables rate limiting globally.
