Rust also offers traits that facilitate type conversions upon implementation. These traits can be found under the [`convert`](https://doc.rust-lang.org/std/convert/index.html) module.
The traits are the following:
- `From` and `Into` covered in [`from_into`](from_into.rs)
- `TryFrom` and `TryInto` covered in [`try_from_into`](try_from_into.rs)
- `AsRef` and `AsMut` covered in [`as_ref_mut`](as_ref_mut.rs)

# Hashmaps
A *hash map* allows you to associate a value with a particular key.
You may also know this by the names [*unordered map* in C++](https://en.cppreference.com/w/cpp/container/unordered_map),
[*dictionary* in Python](https://docs.python.org/3/tutorial/datastructures.html#dictionaries) or an *associative array* in other languages.

Type Option represents an optional value: every Option is either Some and contains a value, or None, and does not.
Option types are very common in Rust code, as they have a number of uses:
- Initial values
- Return values for functions that are not defined over their entire input range (partial functions)
- Return value for otherwise reporting simple errors, where None is returned on error

# Smart Pointers
In Rust, smart pointers are variables that contain an address in memory and reference some other data, but they also have additional metadata and capabilities.
Smart pointers in Rust often own the data they point to, while references only borrow data.

In this way, traits are somewhat similar to Java interfaces and C++ abstract classes.
Some additional common Rust traits include:
- `Clone` (the `clone` method)
- `Display` (which allows formatted display via `{}`)
- `Debug` (which allows formatted display via `{:?}`)
Because traits indicate shared behavior between data types, they are useful when writing generics.
