pub struct ERL { /* private fields */ }Expand description
An edge rate limiter which includes a ratecounter and a penaltybox.
Implementations§
Source§impl ERL
impl ERL
Sourcepub fn open(ratecounter: RateCounter, penaltybox: Penaltybox) -> Self
pub fn open(ratecounter: RateCounter, penaltybox: Penaltybox) -> Self
Open a ERL with the given ratecounter and penaltybox.
Sourcepub fn check_rate(
&self,
entry: &str,
delta: u32,
window: RateWindow,
limit: u32,
ttl: Duration,
) -> Result<bool, ERLError>
pub fn check_rate( &self, entry: &str, delta: u32, window: RateWindow, limit: u32, ttl: Duration, ) -> Result<bool, ERLError>
Increment an entry in a rate counter and check if the client has exceeded some average number of requests per second (RPS) over the window. If the client is over the rps limit for the window, add to the penaltybox for ttl. Valid ttl span is 1m to 1h and TTL value is truncated to the nearest minute.
