The goal of this repo is to make retriving system informations reside in proc file system easier.
minial requirement
rust 2018
supported
I try to make this support any distribution with 3.+ kernel version.
The proc file system is not the same among different version of kernel and distribution. Some code may not works on your system.
Therefore, almost every function return Result for the reason that specified file may not exist in your system. It is possible that specidied file is exist but still return Err. I condider this case as a mistake and should be fix, PR and issue is welcomed.
Majority files listed here shoule be supported. Detail information is listed blow.
