# Std library types

The `std` library provides many custom types which expands drastically on
the `primitives`. Some of these include:

* growable `String`s like: `"hello world"`
* growable vectors: `[1, 2, 3]`
* optional types: `Option<i32>`
* error handling types: `Result<i32, i32>`
* heap allocated pointers: `Box<i32>`
