core::clone::Clone - Rust
Description: API documentation for the Rust `Clone` trait in crate `core`.
Keywords: rust, rustlang, rust-lang, Clone

# 1.0.0[−][src]Trait core::clone::Clone

    #[lang = "clone"]
    pub trait Clone: Sized {
        #[must_use = "cloning is often expensive and is not expected to have side effects"]
    fn clone(&self) -> Self;

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

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

Differs from `Copy` in that `Copy` is implicit and extremely inexpensive, 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.

## 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 an array holding more than 32 elements of a type that is `Clone`; the standard library only implements `Clone` up until arrays of size 32. In this case, the implementation of `Clone` cannot be `derive`d, but can be implemented as:

    #[derive(Copy)]
    struct Stats {
       frequencies: [i32; 100],
    }

    impl Clone for Stats {
        fn clone(&self) -> Stats { *self }
    }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`)
- Array types, for all sizes, if the item type also implements `Clone` (e.g. `[i32; 123456]`)
- Tuple types, if each component also implements `Clone` (e.g. `()`, `(i32, bool)`)
- 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

### `
#[must_use = "cloning is often expensive and is not expected to have side effects"]
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

### `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.

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
