Into_iter
into_iter is a Rust method that consumes or otherwise transforms a value into an iterator yielding its elements, with ownership determined by the receiver.
Idiomatic Rust
into_iter is a method that consumes a collection or other iterable value and returns an iterator that yields its owned elements.
- How it is used
- Uses consuming iteration to move items into iterator chains and to give a linked list an owned-item traversal.
- How deep it goes
- Works through separate iterator structs, `IntoIterator` implementations, and owned-item extraction with `Rc::try_unwrap`.
- Examples
- Shows a consuming linked-list traversal and vectors consumed to unwrap partitioned parsing results.
- What you can do after
- Build it from scratch for a linked list, or apply it to move vector elements through iterator chains.

into_iter is a Rust method that converts a collection or other iterable value into an iterator, with item ownership determined by the receiver.
- How it is used
- Converts vectors into value iterators for loops and iterator chains.
- How deep it goes
- Works through ownership and vector transformations, but does not explain how to implement `into_iter`.
- Examples
- Shows vectors transformed into new vectors and two value iterators zipped into a `HashMap`.
- What you can do after
- Apply it to choose value iteration and recognize when a vector will no longer be available.
