Function core_extensions::collections::clone_this

pub fn clone_this<T>(this: &T) -> T::Owned where
    T: ?Sized + CloneBound, 

Available on crate feature collections only.

For cloning something with either Clone or ToOwned depending on the “alloc” feature.

Features

If the "alloc" feature is disabled then this requires Clone, if it’s enabled this requires ToOwned.

ToOwned is implemented for all types that implement Clone, and you can’t call this function on &str or &[T] arguments without enabling the “alloc” feature.

Examples

use core_extensions::collections::clone_this;

assert_eq!(clone_this(&0), 0);
assert_eq!(clone_this(&"hello"), "hello");

With the “alloc” feature enabled you can clone &str into String, and &[T] into Vec<T>.

use core_extensions::collections::clone_this;

assert_eq!(clone_this("world"), "world".to_string());
assert_eq!(clone_this(&[3, 5, 8][..]), vec![3, 5, 8]);
