A macro for trying to convert an &OsStr to another more usefull type There are lots of ways to do that and this will pick the best via autoref based specialization

e.g. a PathBuf will be created via From<OsString> not From<String> so non UTF8 paths will work.

It is most useful in other macros where you don't know the type you are converting to.

use from_os_str::*;
use std::ffi::OsStr;
use std::path::Path;
let os_str = OsStr::new("123");
let path = try_from_os_str!(os_str as &Path);
assert_eq!(path, Ok(Path::new("123")));
let int = try_from_os_str!(os_str as u8);
assert_eq!(int, Ok(123));

It will use one of the following traits (in order of preferece) to convert the &OsStr to the type you want.

• From<&OsStr>
• From<&Path>
• From
• From<&str>
• From
• TryFrom<&OsStr>
• TryFrom<&str>
• FromStr
