# Enum std::borrow::Cow 1.0.0[−][src]

    pub enum Cow<'a, B> where
        B: 'a + ToOwned + ?Sized,  {
        Borrowed(&'a B),
        Owned(<B as ToOwned>::Owned),
    }

A clone-on-write smart pointer.

The type `Cow` is a smart pointer providing clone-on-write functionality: it can enclose and provide immutable access to borrowed data, and clone the data lazily when mutation or ownership is required. The type is designed to work with general borrowed data via the `Borrow` trait.

`Cow` implements `Deref`, which means that you can call non-mutating methods directly on the data it encloses. If mutation is desired, `to_mut` will obtain a mutable reference to an owned value, cloning if necessary.

If you need reference-counting pointers, note that `Rc::make_mut` and `Arc::make_mut` can provide clone-on-write functionality as well.

# Examples

    use std::borrow::Cow;

    fn abs_all(input: &mut Cow<[i32]>) {
        for i in 0..input.len() {
            let v = input[i];
            if v < 0 {
                // Clones into a vector if not already owned.
                input.to_mut()[i] = -v;
            }
        }
    }

    // No clone occurs because `input` doesn't need to be mutated.
    let slice = [0, 1, 2];
    let mut input = Cow::from(&slice[..]);
    abs_all(&mut input);

    // Clone occurs because `input` needs to be mutated.
    let slice = [-1, 0, 1];
    let mut input = Cow::from(&slice[..]);
    abs_all(&mut input);

    // No clone occurs because `input` is already owned.
    let mut input = Cow::from(vec![-1, 0, 1]);
    abs_all(&mut input);

Run

Another example showing how to keep `Cow` in a struct:

    use std::borrow::Cow;

    struct Items<'a, X: 'a> where [X]: ToOwned<Owned = Vec<X>> {
        values: Cow<'a, [X]>,
    }

    impl<'a, X: Clone + 'a> Items<'a, X> where [X]: ToOwned<Owned = Vec<X>> {
        fn new(v: Cow<'a, [X]>) -> Self {
            Items { values: v }
        }
    }

    // Creates a container from borrowed values of a slice
    let readonly = [1, 2];
    let borrowed = Items::new((&readonly[..]).into());
    match borrowed {
        Items { values: Cow::Borrowed(b) } => println!("borrowed {:?}", b),
        _ => panic!("expect borrowed value"),
    }

    let mut clone_on_write = borrowed;
    // Mutates the data from slice into owned vec and pushes a new value on top
    clone_on_write.values.to_mut().push(3);
    println!("clone_on_write = {:?}", clone_on_write.values);

    // The data was mutated. Let check it out.
    match clone_on_write {
        Items { values: Cow::Owned(_) } => println!("clone_on_write contains owned data"),
        _ => panic!("expect owned data"),
    }

## Variants

`Borrowed(&'a B)`

Borrowed data.

`Owned(<B as ToOwned>::Owned)`

Owned data.

## Implementations

### `impl<'_, B> Cow<'_, B> where
B: ToOwned + ?Sized,` [src]

#### `pub fn is_borrowed(&self) -> bool`[src]

🔬 This is a nightly-only experimental API. (`cow_is_borrowed` #65143)

Returns true if the data is borrowed, i.e. if `to_mut` would require additional work.

# Examples

    #![feature(cow_is_borrowed)]
    use std::borrow::Cow;

    let cow = Cow::Borrowed("moo");
    assert!(cow.is_borrowed());

    let bull: Cow<'_, str> = Cow::Owned("...moo?".to_string());
    assert!(!bull.is_borrowed());

Run

#### `pub fn is_owned(&self) -> bool`[src]

🔬 This is a nightly-only experimental API. (`cow_is_borrowed` #65143)

Returns true if the data is owned, i.e. if `to_mut` would be a no-op.

# Examples

    #![feature(cow_is_borrowed)]
    use std::borrow::Cow;

    let cow: Cow<'_, str> = Cow::Owned("moo".to_string());
    assert!(cow.is_owned());

    let bull = Cow::Borrowed("...moo?");
    assert!(!bull.is_owned());

Run

#### `pub fn to_mut(&mut self) -> &mut <B as ToOwned>::Owned`[src]

Acquires a mutable reference to the owned form of the data.

Clones the data if it is not already owned.

# Examples

    use std::borrow::Cow;

    let mut cow = Cow::Borrowed("foo");
    cow.to_mut().make_ascii_uppercase();

    assert_eq!(
      cow,
      Cow::Owned(String::from("FOO")) as Cow<str>
    );

Run

#### `pub fn into_owned(self) -> <B as ToOwned>::Owned`[src]

Extracts the owned data.

Clones the data if it is not already owned.

# Examples

Calling `into_owned` on a `Cow::Borrowed` clones the underlying data and becomes a `Cow::Owned`:

    use std::borrow::Cow;

    let s = "Hello world!";
    let cow = Cow::Borrowed(s);

    assert_eq!(
      cow.into_owned(),
      String::from(s)
    );

Run

Calling `into_owned` on a `Cow::Owned` is a no-op:

    use std::borrow::Cow;

    let s = "Hello world!";
    let cow: Cow<str> = Cow::Owned(String::from(s));

    assert_eq!(
      cow.into_owned(),
      String::from(s)
    );

Run
