ExpFactor calculates ExpirationFactor based on logOffset.

float64ToFixed64 converts float64 to Fixed64 format.

NewExecQueue creates a new execution Queue.

NewWeightedRandomSelect returns a new WeightedRandomSelect structure.

Uint64ToFixed64 converts uint64 integer to Fixed64 format.

ExecQueue implements a queue that executes function calls in a single thread, in the same order as they have been queued.

ExpirationFactor is calculated from logOffset.

ExpiredValue is a scalar value that is continuously expired (decreased exponentially) based on the provided logarithmic expiration offset value.

Expirer changes logOffset with a linear rate which can be changed during operation.

LinearExpiredValue is very similar with the expiredValue which the value will continuously expired.

ValueExpirer controls value expiration rate.

Fixed64 implements 64-bit fixed point arithmetic functions.
