Searching with Iterators using Structs
Learn about Rust's core concepts such as iterators and pattern matching in a struct.
We'll cover the following...
Though visitors are now represented as structures, we still need to be able to search them. We could use the same search code as before, comparing your_name with visitor.name to call the greeting method directly, but this method isn’t ideal. This gets unwieldy as our visitors become more complicated and we add more visitors to the list.

Rust provides a powerful feature known as iterators to manipulate data. Iterators can do a lot.
When working with lists of data, iterators are the first place to look for the functionality we need. Iterators are designed around function chaining. Each iterator step works as a building block to massage the data ...
