leaky-bucket-lite
A token-based rate limiter based on the leaky bucket algorithm, mainly a lazy reimplementation of udoprog's leaky-bucket with less dependencies and overhead.
If the tokens are already available, the acquisition will be instant through a fast path, and the acquired number of tokens will be added to the bucket.
If they aren't, the task that tried to acquire the tokens will be suspended until the required number of tokens has been added.
Usage
Add the following to your Cargo.toml
:
= "0.3"
Features
leaky-bucket-lite provides 3 implementations:
leaky_bucket_lite::LeakyBucket
(thread-safe, available via thetokio
feature, which is on by default)leaky_bucket_lite::sync_threadsafe::LeakyBucket
(thread-safe, available via thesync-threadsafe
featureleaky_bucket_lite::sync::LeakyBucket
(not thread-safe, available via thesync
feature).
For potential performance increase with sync-threadsafe
using parking_lot
's locking objects, enable the parking-lot
feature.
Example
use LeakyBucket;
use ;
