kolimiter

kolimiter is a Go package that provides a token bucket rate limiting implementation. It allows developers to control the rate at which operations can be performed, preventing services from being overwhelmed by too many requests. The package is designed to be efficient and easy to use.

The core concept behind kolimiter is the token bucket algorithm. Imagine a bucket that holds a certain number of tokens. Tokens are added to the bucket at a fixed rate. To perform an operation, a token must be taken from the bucket. If the bucket is empty, the operation must wait until a new token becomes available. This mechanism effectively limits the rate of operations to the rate at which tokens are replenished.

kolimiter offers several options for configuring the rate limiter, including the capacity of the bucket and the rate at which tokens are added. It supports different types of rate limiters, such as `Rate` and `StdRate`, allowing for flexible configuration. The package also provides methods for acquiring tokens, such as `Allow()`, `Wait()`, and `Reserve()`, which offer different behaviors for handling situations where tokens are not immediately available. These methods allow for fine-grained control over how rate limiting is applied in an application. kolimiter is a popular choice for implementing rate limiting in Go applications due to its performance and straightforward API.
