Struct LogSuppresser

Source 
pub struct LogSuppresser {
    suppressed_count: AtomicUsize,
    rate_limiter: RateLimiter<NotKeyed, InMemoryState, MonotonicClock>,
}
Expand description

LogSuppresser is a helper to suppress log spamming.

Fields§

§suppressed_count: AtomicUsize

The number of times the log has been suppressed. Will be returned and cleared when the rate limiter allows next log to be printed.

§rate_limiter: RateLimiter<NotKeyed, InMemoryState, MonotonicClock>

Inner rate limiter.

Implementations§

Source§

impl LogSuppresser

Source

pub fn new( rate_limiter: RateLimiter<NotKeyed, InMemoryState, MonotonicClock>, ) -> Self

Source

pub fn check(&self) -> Result<Option<NonZeroUsize>, LogSuppressed>

Check if the log should be suppressed. If the log should be suppressed, return Err(LogSuppressed). Otherwise, return Ok(Some(..)) with count of suppressed messages since last check, or Ok(None) if there’s none.
