Hello World!
This is a basic example how to use Rust to write your RIOT application.
It prints out the famous text Hello World!.
This example should foremost give you an overview how an application built completely in Rust is structured:
-
The Makefile resembles the regular application Makefile, see ../hello-world/ for more introduction to that.
-
The Cargo.toml file describes the Rust code, and declares its dependencies.
Prominently, it contains a
[lib]/crate-type = ["staticlib"]section, which is necessary for how RIOT later links together the C and Rust portions. -
The file src/lib.rs (and any modules referenced by it) contain Rust code to be run.
It uses the
riot_main!macro provided by the riot-wrappers crate to declare the entry point of the program.
The code itself looks like the usual Rust hello-world example.
