Trait af_core::iter::__std_iter::IntoIterator 1.0.0[−][src]
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());
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<Self::Item>; 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); }
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() }
Associated Types
type Item

Which kind of iterator are we turning this into?
Required methods
#[lang = "into_iter"]pub fn into_iter(self) -> Self::IntoIter
