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"), }Run
Variants
Borrowed(&'a B)Borrowed data.
Owned data.
Implementations
impl<'_, B> Cow<'_, B> where
B: ToOwned + ?Sized, [src]
impl<'_, B> Cow<'_, B> where
B: ToOwned + ?Sized, [src]pub const fn is_borrowed(&self) -> bool[src]
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 const fn is_owned(&self) -> bool[src]
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

If s is borrowing a slice, a new Vec<T> will be allocated and
filled by cloning s’s items into it.
