//! use std::os::unix::ffi::OsStringExt;
//!
//! let bytes = b"foo".to_vec();
//!
//! // OsStringExt::from_vec
//! let os_string = OsString::from_vec(bytes);
//! assert_eq!(os_string.to_str(), Some("foo"));
//!
//! // OsStringExt::into_vec
//! let bytes = os_string.into_vec();
//! assert_eq!(bytes, b"foo");
//! ```
//!
//! ```
//! use std::ffi::OsStr;
//! use std::os::unix::ffi::OsStrExt;
//!
//! let bytes = b"foo";
//!
//! // OsStrExt::from_bytes
//! let os_str = OsStr::from_bytes(bytes);
//! assert_eq!(os_str.to_str(), Some("foo"));
