# Blocking vs Non-blocking

The default behavior of the ring buffer is non-blocking, 
meaning that reads and writes will return immediately with an error if the operation cannot be completed.
If you want to block when reading or writing, you must enable it:

```go
	rb := ringbuffer.New(1024).SetBlocking(true)
```

Enabling blocking will cause the ring buffer to behave like a buffered [io.Pipe](https://pkg.go.dev/io#Pipe).
