Client indicates the redis client of the rate limiter.

Every converts a minimum time interval between events to a Limit.

NewLimiter returns a new Limiter that allows events up to rate r and permits bursts of at most b tokens.

SetRedis sets the redis client.

Inf is the infinite rate limit; it allows all events (even if burst is zero).

A Limiter controls how frequently events are allowed to happen.

A Reservation holds information about events that are permitted by a Limiter to happen after a delay.

Limit defines the maximum frequency of some events.
