Key points:
|

|
||||
* Zero-cost abstractions, similar to C++, means that you don't have to 'pay'
|
||||
for higher-level programming constructs with memory or CPU. For example,
|
||||
writing a loop using `for` should result in roughly the same low level
|
||||
instructions as using the `.iter().fold()` construct.
|

|

* It may be worth mentioning that Rust enums are 'Algebraic Data Types', also
|
||||
known as 'sum types', which allow the type system to express things like
|
||||
`Option<T>` and `Result<T, E>`.
|

|

* Remind people to read the errors --- many developers have gotten used to
|

ignore lengthly compiler output. The Rust compiler is significantly more

talkative than other compilers. It will often provide you with _actionable_
