wmi

WMI (Windows Management Instrumentation) crate for rust.

```toml

Cargo.toml

[dependencies] wmi = "0.8" ```

Examples

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

```rust

![allow(noncamelcase_types)]

![allow(nonsnakecase)]

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

fn main() -> Result<(), Box> { let comcon = COMLibrary::new()?; let wmicon = 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(())

} ```

Async Queries

WMI supports async queries, with methods like ExecAsyncQuery.

This crate provides async methods under the async-query flag:

```toml

Cargo.toml

[dependencies] wmi = { version = "0.8", features = ["async-query"] } ```

The methods become available on WMIConnection

```rust

![allow(noncamelcase_types)]

![allow(nonsnakecase)]

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

fn main() -> Result<(), Box> { let comcon = COMLibrary::new()?; let wmicon = WMIConnection::new(com_con.into())?;

block_on(exec_async_query(&wmi_con))?;

Ok(())

}

async fn execasyncquery(wmicon: &WMIConnection) -> Result<(), Box> { let results: Vec> = wmicon.asyncrawquery("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(())

} ```
