Basic Syntax

[QED Smart Contract Language] uses a syntax inspired by [Rust]. Here are the basics:

Variables

Variables are declared with let and can be mutable with mut:

#![allow(unused)]
fn main() {
let a: Felt = 1;
let mut b: Felt = 2;
b += 1;

}

Comments

Use // for single-line comments: Use /* */ for single-line comments:

#![allow(unused)]
fn main() {
// This is a comment
let a: Felt = 1;
}
