wmi
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(())
