the missing go error package.

EnableLockTracker enable lock tracking background worker.

HashedID creates a hashed ID from a unique string.

race retries if the function takes too long to return |---------------- attempt 1 ----------------| | delay |--------- attempt 2 ---------|.

NewLeakyBucket initiates LeakyBucket with rateLimit, slack, and clock.

NewProtoProxy creates a new ProtoProxy that regenerates underlying values at a cadence of refreshInterval this should be used for updates that should be sent periodically, but does not have the urgency of immediate delivery updateFn should provide computations required to generate the protobuf if refreshInterval is 0, then proxy will only update on MarkDirty(true).

ParallelExec will executes the given function with each element of vals, if len(vals) >= parallelThreshold, will execute them in parallel, with the given step size.

ScanTrackedLocks check all lock trackers.

ScanTrackedLocksI check lock trackers incrementally n at a time.

a ring buffer of welford mean/var summaries used to aggregate jitter and rtt.

ProtoProxy is a caching proxy for protobuf messages that may be expensive to compute.
