query_wmi

A crate to query WMI classes in windows

Windows Management Instrumentation (WMI) is the infrastructure for management data and operations on Windows-based operating systems. You can write WMI scripts or applications to automate administrative tasks on remote computers, but WMI also supplies management data to other parts of the operating system and products—for example, System Center Operations Manager (formerly Microsoft Operations Manager (MOM)), or Windows Remote Management (WinRM). Usage:

use query_wmi::{COMLibrary, Variant, WMIConnection};
use query_wmi::computer_hardware::{
    get_Win32_CDROMDrive, get_Win32_ComputerSystem,
    get_Win32_PCMCIAController, get_Win32_PnPEntity, get_Win32_Processor,
    get_Win32_SystemEnclosure, get_Win32_TapeDrive, get_Win32_USBHub,
};
use query_wmi::operating_systems::get_Win32_OperatingSystem;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let com_con = COMLibrary::new()?;
    dbg!(get_Win32_OperatingSystem(com_con)?);
    dbg!(get_Win32_CDROMDrive(com_con)?);
    dbg!(get_Win32_ComputerSystem(com_con)?);
    dbg!(get_Win32_PCMCIAController(com_con)?);
    dbg!(get_Win32_PnPEntity(com_con)?);
    dbg!(get_Win32_Processor(com_con)?);
    dbg!(get_Win32_SystemEnclosure(com_con)?);
    dbg!(get_Win32_USBHub(com_con)?);
    dbg!(get_Win32_TapeDrive(com_con)?);
    Ok(())
}

Return type

type Query = Vec<HashMap<String, Variant>>.

String is the name of the returned struct field with Variant being an enum type.

Building your own class queries

You can use the provided wmi macro to make your own queries:

#![allow(non_snake_case)]

use query_wmi::wmi;
use query_wmi::Query;
use paste::paste;
use std::collections::HashMap;
use query_wmi::COMLibrary;
use query_wmi::{Variant, WMIConnection};

// this creates the function `get_CLASS_NAME()`
wmi! {
    /// Documentation
    CLASS_NAME, r"path_to_namespace"
}

// calling it
let com_con = COMLibrary::new() ?;
dbg!(get_CLASS_NAME(com_con)?);
