windows-result 0.100.0

windows-result

The windows-result crate provides Windows error types for Win32, COM, and WinRT APIs.

• Getting started

Start by adding the following to your Cargo.toml file:

[dependencies.windows-result]
version = "0.100"

Use the HRESULT, Error, and specialized Result types as needed:

use windows_result::*;

const S_OK: HRESULT = HRESULT(0);
const ERROR_CANCELLED: WIN32_ERROR = WIN32_ERROR(1223);
const E_CANCELLED: HRESULT = ERROR_CANCELLED.to_hresult();

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(())
}
