//! Cross-platform alternative to file descriptors.
//!
//! You most likely won't ever need to use this: `#[derive(Object)]` shall take care of serializing
//! and deserializing [`std::fs::File`] and similar objects. If, however, you store raw file
//! descriptors and implement serialization yourself, using this module might be a sane choice.

use std::os::windows::io;
use windows::Win32::Foundation::HANDLE;

// We use HANDLE from 'windows' crate instead of io::RawHandle because the latter is just an alias
// to a pointer and not a newtype, so if we implement traits for it, chaos is likely to ensue. Also,
// *mut c_void is not Sync + Send, so lazy_static! and coroutines (likely) fail.
