* samples: rust: print: Add sample code for Arc printingBoqun Feng2023-04-101-0/+26
| | | | | | | | | | | | | | | | This both demonstrates the usage of different print format in Rust and serves as a selftest for the `Display` and `Debug` implementation of `Arc` and its friends.

* rust: macros: take string literals in `module!`Gary Guo2022-12-042-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of taking binary string literals, take string ones instead, making it easier for users to define a module, i.e. instead of calling `module!` like: module! { ... name: b"rust_minimal", ... } now it is called as: module! { ... name: "rust_minimal", ... } Module names, aliases and license strings are restricted to ASCII only. However, the author and the description allows UTF-8. For simplicity (avoid parsing), escape sequences and raw string literals are not yet handled.

* samples: add first Rust examplesMiguel Ojeda2022-09-288-0/+105
The beginning of a set of Rust modules that showcase how Rust modules look like and how to use the abstracted kernel features. It also includes an example of a Rust host program with several modules. These samples also double as tests in the CI.
