Implementations

impl Ratelimit

pub fn new() -> Self

pub fn ratelimit_set_speed(&mut self, speed: u64)

pub fn ratelimit_calculate_delay(&mut self, n: u64) -> u64

Calculate and return delay for next request in ns Record that we sent n data units (where n matches the scale chosen during ratelimit_set_speed).If we may send more data units in the current time slice, return 0 (i.e. no delay). Otherwise return the amount of time (in ns) until the start of the next time slice that will permit sending the next chunk of data.

Recording sent data units even after exceeding the quota is permitted; the time slice will be extended accordingly.
