Crate psutil

A process and system monitoring library for Rust, heavily inspired by the psutil module for Python.

Minimum versions supported

• Linux: 2.6.0 (2003-12-17)

Note about the API

rust-psutil implements the same API as psutil with some exceptions:

• some things have been slightly renamed
• the crate is namespaced based on subsystem, e.g. cpu::cpu_percent()
  • users can opt into which subsystems to use based on cargo feature flags
• some functions have been refactored
  • e.g. cpu_count(bool) into cpu_count() and cpu_count_physical()
• functions that need to persist data between calls are implemented as methods on ‘collectors’
  • e.g. cpu_percent() -> CpuPercentCollector::cpu_percent()
• platform specific functionality is hidden behind traits that need to be imported before used
  • e.g. import cpu::os::linux::ProcessExt to use Linux specific process functionality
• some types are different, for example:
  • structs instead of named tuples
  • std::time::Duration instead of float for seconds
  • enums instead of constants
• most struct fields have been replaced with getter methods to better enable platform based extensions
