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

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);
