# 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).

	for scanner.Scan() {
		f := strings.Fields(scanner.Text())
		if len(f) < 3 {
			continue
		}
		syms[f[2]] = f[0]
	}
	if err := scanner.Err(); err != nil {
		t.Fatalf("error reading symbols: %v", err)
	}
	return syms
}

	for readTrigger := range readTriggerCh {
		newBufLK.RLock()
		canDecode := p.canDecode(newBuf)
		newBufLK.RUnlock()

### Troubleshooting

1. Valid cacheable responses are not being cached

Make sure you are reading responses fully as unless they are read fully, cancelled or stalled Responses will not be cached.

### Overriding normal cache behaviour

pkg context, type CancelFunc func()
