Expand description

Helper struct for safely printing an `OsStr` with `format!` and `{}`.

An `OsStr` might contain non-Unicode data. This `struct` implements the `Display` trait in a way that mitigates that. It is created by the `display` method on `OsStr`. This may perform lossy conversion, depending on the platform. If you would like an implementation which escapes the `OsStr` please use `Debug` instead.

## §Examples

    use std::ffi::OsStr;

    let s = OsStr::new("Hello, world!");
    println!("{}", s.display());
