[−][src]Function libpijul::path::parent
pub fn parent(path: &str) -> Option<&str>
Returns the parent of the path, if it exists. This function tries
to replicate the behaviour of std::path::Path::parent, but with
&str instead of Path.
ⓘThis example is not tested
use libpijul::path::parent; assert_eq!(parent("/foo/bar"), Some("/foo")); assert_eq!(parent("foo"), Some("")); assert_eq!(parent("/"), None); assert_eq!(parent(""), None);
