Module perfcnt::linux::parser
[−]
[src]
Uses the nom library to parse the in memory format of perf data structures and
transforms them into more rust-like data-strutures.
References
The code is inspired by the following articles and existing parser to make sense of the (poorly documented) format:
- https://lwn.net/Articles/644919/
- http://man7.org/linux/man-pages/man2/perf_event_open.2.html
- https://github.com/andikleen/pmu-tools/tree/master/parser
Current limitations
- Only version 2 of the data format
- No support for AUX stuff
- Sample ID at the end of records is currently ignored
- I'm not sure if I'm parsing the BuildId correctly, it seems it can not be recognized
- Only support little endian machines
