Windows error handling
The windows-result crate provides efficient Windows error handling and propagation with support for Win32, COM, and WinRT APIs.
Start by adding the following to your Cargo.toml file:
[dependencies.windows-result]
version = "0.3"
Use the HRESULT
, Error
, and specialized Result
types as needed:
use windows_result::*;
const S_OK: HRESULT = HRESULT(0);
const ERROR_CANCELLED: u32 = 1223;
const E_CANCELLED: HRESULT = HRESULT::from_win32(ERROR_CANCELLED);
fn main() -> Result<()> {
S_OK.ok()?;
let e = Error::new(E_CANCELLED, "test message");
assert_eq!(e.code(), E_CANCELLED);
assert_eq!(e.message(), "test message");
Ok(())
}
