# 1.0.0[−][src]Trait core::iter::IntoIterator

    pub trait IntoIterator {
        type Item;
        type IntoIter: Iterator<Item = Self::Item>;
        fn into_iter(self) -> Self::IntoIter;
    }

Conversion into an `Iterator`.

By implementing `IntoIterator` for a type, you define how it will be converted to an iterator. This is common for types which describe a collection of some kind.

One benefit of implementing `IntoIterator` is that your type will work with Rust's `for` loop syntax.

See also: `FromIterator`.

# Examples

Basic usage:

    let v = vec![1, 2, 3];
    let mut iter = v.into_iter();

    assert_eq!(Some(1), iter.next());
    assert_eq!(Some(2), iter.next());
    assert_eq!(Some(3), iter.next());
    assert_eq!(None, iter.next());Run

Implementing `IntoIterator` for your type:

    // A sample collection, that's just a wrapper over Vec<T>
    #[derive(Debug)]
    struct MyCollection(Vec<i32>);

    // Let's give it some methods so we can create one and add things
    // to it.
    impl MyCollection {
        fn new() -> MyCollection {
            MyCollection(Vec::new())
        }

        fn add(&mut self, elem: i32) {
            self.0.push(elem);
        }
    }

    // and we'll implement IntoIterator
    impl IntoIterator for MyCollection {
        type Item = i32;
        type IntoIter = ::std::vec::IntoIter<i32>;

        fn into_iter(self) -> Self::IntoIter {
            self.0.into_iter()
        }
    }

    // Now we can make a new collection...
    let mut c = MyCollection::new();

    // ... add some stuff to it ...
    c.add(0);
    c.add(1);
    c.add(2);

    // ... and then turn it into an Iterator:
    for (i, n) in c.into_iter().enumerate() {
        assert_eq!(i as i32, n);
    }Run

It is common to use `IntoIterator` as a trait bound. This allows the input collection type to change, so long as it is still an iterator. Additional bounds can be specified by restricting on `Item`:

    fn collect_as_strings<T>(collection: T) -> Vec<String>
        where T: IntoIterator,
              T::Item : std::fmt::Debug,
    {
        collection
            .into_iter()
            .map(|item| format!("{:?}", item))
            .collect()
    }Run

## Associated Types

### `type Item`

The type of the elements being iterated over.

### `type IntoIter: Iterator<Item = Self::Item>`

Which kind of iterator are we turning this into?

## Required Methods

### `fn into_iter(self) -> Self::IntoIter`

Creates an iterator from a value.

See the module-level documentation for more.

# Examples

Basic usage:

    let v = vec![1, 2, 3];
    let mut iter = v.into_iter();

    assert_eq!(Some(1), iter.next());
    assert_eq!(Some(2), iter.next());
    assert_eq!(Some(3), iter.next());
    assert_eq!(None, iter.next());Run

`fn into_iter(self) -> IntoIter<T>`

[src]

Returns a consuming iterator over the possibly contained value.

# Examples

    let x = Some("string");
    let v: Vec<&str> = x.into_iter().collect();
    assert_eq!(v, ["string"]);

    let x = None;
    let v: Vec<&str> = x.into_iter().collect();
    assert!(v.is_empty());Run

`impl<T> Iterator for IntoIter<T> type Item = T;`

`fn into_iter(self) -> IntoIter<T>`

[src]

Returns a consuming iterator over the possibly contained value.

The iterator yields one value if the result is `Result::Ok`, otherwise none.

# Examples

Basic usage:

    let x: Result<u32, &str> = Ok(5);
    let v: Vec<u32> = x.into_iter().collect();
    assert_eq!(v, [5]);

    let x: Result<u32, &str> = Err("nothing!");
    let v: Vec<u32> = x.into_iter().collect();
    assert_eq!(v, []);Run

## 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`)
