    pub trait Clone: Sized {
        // Required method
        fn clone(&self) -> Self;

        // Provided method
        fn clone_from(&mut self, source: &Self) { ... }
    }

Expand description

A common trait for the ability to explicitly duplicate an object.

Differs from `Copy` in that `Copy` is implicit and an inexpensive bit-wise copy, while `Clone` is always explicit and may or may not be expensive. In order to enforce these characteristics, Rust does not allow you to reimplement `Copy`, but you may reimplement `Clone` and run arbitrary code.

Since `Clone` is more general than `Copy`, you can automatically make anything `Copy` be `Clone` as well.

### §Derivable

This trait can be used with `#[derive]` if all fields are `Clone`. The `derive`d implementation of `Clone` calls `clone` on each field.

For a generic struct, `#[derive]` implements `Clone` conditionally by adding bound `Clone` on generic parameters.

    // `derive` implements Clone for Reading<T> when T is Clone.
    #[derive(Clone)]
    struct Reading<T> {
        frequency: T,
    }

Run

### §How can I implement `Clone`?

Types that are `Copy` should have a trivial implementation of `Clone`. More formally: if `T: Copy`, `x: T`, and `y: &T`, then `let x = y.clone();` is equivalent to `let x = *y;`. Manual implementations should be careful to uphold this invariant; however, unsafe code must not rely on it to ensure memory safety.

An example is a generic struct holding a function pointer. In this case, the implementation of `Clone` cannot be `derive`d, but can be implemented as:

    struct Generate<T>(fn() -> T);

    impl<T> Copy for Generate<T> {}

    impl<T> Clone for Generate<T> {
        fn clone(&self) -> Self {
            *self
        }
    }

Run

If we `derive`:

    #[derive(Copy, Clone)]
    struct Generate<T>(fn() -> T);

Run

the auto-derived implementations will have unnecessary `T: Copy` and `T: Clone` bounds:

    // Automatically derived
    impl<T: Copy> Copy for Generate<T> { }

    // Automatically derived
    impl<T: Clone> Clone for Generate<T> {
        fn clone(&self) -> Generate<T> {
            Generate(Clone::clone(&self.0))
        }
    }

Run

The bounds are unnecessary because clearly the function itself should be copy- and cloneable even if its return type is not:

ⓘ

    #[derive(Copy, Clone)]
    struct Generate<T>(fn() -> T);

    struct NotCloneable;

    fn generate_not_cloneable() -> NotCloneable {
        NotCloneable
    }

    Generate(generate_not_cloneable).clone(); // error: trait bounds were not satisfied
    // Note: With the manual implementations the above line will compile.

Run

### §Additional implementors

In addition to the implementors listed below, the following types also implement `Clone`:

- Function item types (i.e., the distinct types defined for each function)
- Function pointer types (e.g., `fn() -> i32`)
- Closure types, if they capture no value from the environment or if all such captured values implement `Clone` themselves. Note that variables captured by shared reference always implement `Clone` (even if the referent doesn’t), while variables captured by mutable reference never implement `Clone`.

## Required Methods§

source

#### fn clone(&self) -> Self

Returns a copy of the value.

##### §Examples

    let hello = "Hello"; // &str implements Clone

    assert_eq!("Hello", hello.clone());

Run

## Provided Methods§

source

#### fn clone_from(&mut self, source: &Self)

Performs copy-assignment from `source`.

`a.clone_from(&b)` is equivalent to `a = b.clone()` in functionality, but can be overridden to reuse the resources of `a` to avoid unnecessary allocations.

## Object Safety§

This trait is not object safe.
