### Important traits for SplitPaths<'a>

`impl<'a> Iterator for SplitPaths<'a> type Item = PathBuf;`

    pub fn split_paths<T: AsRef<OsStr> + ?Sized>(unparsed: &T) -> SplitPaths

Parses input according to platform conventions for the `PATH` environment variable.

Returns an iterator over the paths contained in `unparsed`.

# Examples

    use std::env;

    let key = "PATH";
    match env::var_os(key) {
        Some(paths) => {
            for path in env::split_paths(&paths) {
                println!("'{}'", path.display());
            }
        }
        None => println!("{} is not defined in the environment.", key)
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
