# simple-process-stats

A small library to get memory usage and elapsed CPU time.

Supports Windows, Linux and macOS.

```rust

use simple_process_stats::ProcessStats;

let process_stats = ProcessStats::get().expect("could not get stats for running process");

println!("{:?}", process_stats);

// ProcessStats {

//     cpu_time_user: 421.875ms,

//     cpu_time_kernel: 102.332ms,

//     memory_usage_bytes: 3420160,

// }

```

On Linux, this library reads `/proc/self/stat` and uses the `sysconf` libc function.

On Windows, the library uses `GetCurrentProcess` combined with `GetProcessTimes` and `K32GetProcessMemoryInfo`.

On macOS, this library uses `proc_pidinfo` from `libproc` (and current process ID is determined via `libc`).
