Struct AccessPattern 

pub struct AccessPattern { /* private fields */ }

Records how a file is accessed. For security sake, each file can associate an access pattern recorder, which is globally configured through nydusd configuration file. For now, the pattern is composed of: 1. How many times a file is read regardless of io block size and request offset. And this counter can not be cleared. 2. First time point at which this file is read. It’s wall-time in unit of seconds. 3. File path relative to current rafs root.

Yes, we now don’t have an abundant pattern recorder now. It can be negotiated in the future about how to enrich it.
