type TokenBucket ¶

type TokenBucket struct {
	// contains filtered or unexported fields
}

TokenBucket is a token bucket rate limiter used to limit the frequency of requests. Its working principle is: over a period of time, it generates a certain number of tokens. For each request, if the number of tokens is ≥1, the request is allowed; otherwise, it is rejected. This ensures that the request frequency does not exceed the specified rate over a period of time.
