Crate from_os_str
source · [−]Expand description
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.
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));
