Const And Static

% const and static

<small>There is a new edition of the book and this is an old link.</small>

Constants are always immutable, and may only be set to a constant expression, not the result of a function call or any other value that could only be computed at runtime.

Global variables are called static in Rust.

const MAX_POINTS: u32 = 100_000;
static HELLO_WORLD: &str = "Hello, world!";
