How to create a static array of strings?

Question

Note This question contains syntax that predates Rust 1.0. The code is invalid, but the concepts are still relevant.

How do

Answer 1

There are two related concepts and keywords in Rust: const and static:

https://doc.rust-lang.org/reference/items/constant-items.html

For most use cases, including this one, const is more appropriate, since mutation is not allowed, and the compiler may inline const items.

const STRHELLO:&'static str = "Hello";
const STRWORLD:&'static str = "World";
const ARR:[&'static str, ..2] = [STRHELLO,STRWORLD];

Note, there is some out-of-date documentation out there that doesn't mention the newer const, including Rust by Example.
