whats the difference between Iter and into_iter rust
The Iter
and IntoIter
types in Rust are both iterators, but they have some differences in how they work.
The Iter
type is a reference-based iterator, meaning it borrows the elements from the collection it iterates over. It is created by calling the iter
method on a collection. The Iter
type provides read-only access to the elements, allowing you to iterate over them and perform operations on them, but you cannot modify the original collection through the Iter
.
On the other hand, the IntoIter
type is an owned iterator, meaning it takes ownership of the elements from the collection. It is created by calling the into_iter
method on a collection. The IntoIter
type allows you to both read and modify the elements, as it has full ownership over them. This means you can mutate the original collection through the IntoIter
.
In summary, the main difference between Iter
and IntoIter
in Rust is the ownership semantics. Iter
borrows the elements from the collection, providing read-only access, while IntoIter
takes ownership of the elements, allowing both read and write access.
It's worth noting that these are just conventions and not hard rules. The specific behavior can vary depending on the implementation of the iterator for a particular collection type in Rust.
