PowerShell System Stats

Using a Rust library and FFI from .NET displays basic system stats in PowerShell

Contents

• GetSystemStats - PowerShell binary Cmdlet with supporting classes and functions for FFI to Rust
• GetSystemStatsTest - XUnit tests for GetSystemStats
• system-stats - Rust based library of functions called from GetSystemStats

Intentions

Simple, experiment with C# FFI to Rust, wrapped in a PowerShell Cmdlet. PowerShell provides a nice CLI user interface for administrators and operators. Additionally generally annoying that Windows CLI/PowerShell doesn't provide a handy way to check resource usage in your shell.

TODO

• PowerShell built in help
• Rust Documentation
• PowerShell default output formatting
• Refactor SystemStatWarapper so each handle is it's own class
• Output number formatting

Usage and Build

• Install Rust toolchain, .NET SDK 5, PowerShell 7 on your amd_64 platform of choice
• Build all the things, a sample PowerShell script to build is in Start-Build.ps1.
• May need to adjust the build process for your platform specifics.
