Struct RateCounter

pub struct RateCounter { /* private fields */ }

A rate counter tracks the number of transfers, the amount of data exchanged and the rate of transfer (via a few timers) over the last minute. The counter does not try to be accurate and update times proactively, instead it only does so lazily. As a result, produced rates are worst-case estimates.

Implementations

impl RateCounter

pub fn new() -> RateCounter

Instantiate a new rate counter

pub fn inc(&mut self, bytes: u64)

Increments number of bytes transferred, updating counts and rates.

pub fn inc_quiet(&mut self, bytes: u64)

Increments number of bytes without updating the count or rate. We filter out 0 last_min_times when calculating rate. Used during txhashset.zip download to track bytes downloaded without treating a peer as abusive (too high a rate of download).

pub fn bytes_per_min(&self) -> u64

Number of bytes counted in the last minute. Includes “quiet” byte increments.

pub fn count_per_min(&self) -> u64

Count of increases in the last minute. Excludes “quiet” byte increments.

pub fn elapsed_since_last_msg(&self) -> Option<u64>

Elapsed time in ms since the last entry. We use this to rate limit when sending.
