Hello, world!

"Hello, world!" projects are a common starting point for developers learning new languages or platforms, as it provides a simple demonstration of how a programming language can be written for an application.

This variation of "Hello, world!" is written in Rust,a programming language designed specifically for developing canisters on ICP. Smart contracts on ICP are called canisters.

Project structure

The /backend folder contains the Rust smart contract:

• Cargo.toml, which defines the crate that will form the backend
• lib.rs, which contains the actual smart contract, and exports its interface
