Command line arguments by reference

The standard library's std::env::args_os iterator produces an owned string (OsString) for each argument. In some use cases it can be more convenient for the arguments to be produced by static reference (&'static OsStr).

[dependencies]
argv = "0.1"

Example

fn main() {
    for arg in argv::iter() {
        // arg is a &'static OsStr.
        println!("{}", arg.to_string_lossy());
    }
}

Portability

This crate is intended to be used on Linux and macOS, on which command line arguments naturally live for the duration of the program. This crate implements the same API on other platforms as well, such as Windows, but leaks memory on platforms other than Linux and macOS.
