Rust allows you to define types called "enums" which enumerate possible values.

Enums are a feature in many languages, but their capabilities differ in each language. Rust’s enums are most similar to algebraic data types in functional languages, such as F#, OCaml, and Haskell.

# Async
|
||||
|
||||
Rust includes built-in support for asynchronous programming. In other languages, this might be known as Promises or
|
||||
Coroutines. async programming uses async functions, which are powerful, but may require some getting used to,
|
||||
especially if you haven't used something similar in another language.
|
||||
|
||||
The [relevant book chapter][1] is essential reading. The [tokio docs][2] are also very helpful!
