tcprate

Minimalistic rate limiter for TCP servers.

Aimed to follow the public contracts of net.Listener and net.Conn as much as possible.

Usage

lis, err := net.Listen("tcp", ":")
if err != nil {
    log.Fatal(err)
}
// Wrap the listener.
lim := tcprate.NewListener(lis)
// Set 64 KB/sec global limit and 4 KB/sec limit per connection.
lim.SetLimits(64*1024, 4*1024)
// Now lim can be used as any net.Listener.
// ...

Known Limitations

• The rate limit is only applied to outbound server traffic.
• Write errors are ignored when calculating the rate limit.
• Both tests and functionality are minimal.
