wmi

checkcrates.io docs.rs

WMI (Windows Management Instrumentation) crate for rust.

# Cargo.toml
[dependencies]
wmi = "0.13"

Examples

Queries can be deserialized into a free-form HashMap or a struct:

#![allow(non_camel_case_types)]
#![allow(non_snake_case)]

use serde::Deserialize;
use wmi::{COMLibrary, Variant, WMIConnection, WMIDateTime};
use std::collections::HashMap;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let com_con = COMLibrary::new()?;
    let wmi_con = WMIConnection::new(com_con.into())?;

    let results: Vec<HashMap<String, Variant>> = wmi_con.raw_query("SELECT * FROM Win32_OperatingSystem")?;

    for os in results {
        println!("{:#?}", os);
    }

    #[derive(Deserialize, Debug)]
    struct Win32_OperatingSystem {
        Caption: String,
        Name: String,
        CurrentTimeZone: i16,
        Debug: bool,
        EncryptionLevel: u32,
        ForegroundApplicationBoost: u8,
        LastBootUpTime: WMIDateTime,
    }

    let results: Vec<Win32_OperatingSystem> = wmi_con.query()?;

    for os in results {
        println!("{:#?}", os);
    }

    Ok(())
}

chrono vs time

If you prefer to use the time crate instead of the default chrono, include wmi as

[dependencies]
wmi-rs = { version = "*", default-features = false, features = ["time"] }

and use the WMIOffsetDateTime wrapper instead of the WMIDateTime wrapper.

Async Queries

WMI supports async queries, with methods like ExecAsyncQuery.

#![allow(non_camel_case_types)]
#![allow(non_snake_case)]

use serde::Deserialize;
use wmi::{COMLibrary, Variant, WMIConnection, WMIDateTime};
use std::collections::HashMap;
use futures::executor::block_on;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let com_con = COMLibrary::new()?;
    let wmi_con = WMIConnection::new(com_con.into())?;

    block_on(exec_async_query(&wmi_con))?;

    Ok(())
}

async fn exec_async_query(wmi_con: &WMIConnection) -> Result<(), Box<dyn std::error::Error>> {
    let results: Vec<HashMap<String, Variant>> =
        wmi_con.async_raw_query("SELECT * FROM Win32_OperatingSystem").await?;

    for os in results {
        println!("{:#?}", os);
    }

    #[derive(Deserialize, Debug)]
    struct Win32_OperatingSystem {
        Caption: String,
        Name: String,
        CurrentTimeZone: i16,
        Debug: bool,
        EncryptionLevel: u32,
        ForegroundApplicationBoost: u8,
        LastBootUpTime: WMIDateTime,
    }

    let results: Vec<Win32_OperatingSystem> = wmi_con.async_query().await?;

    for os in results {
        println!("{:#?}", os);
    }

    Ok(())
}
