Nightly tool chains allow for the development of libraries and applations including `unsafe` code (which will be necessary for the later excercises). For some tools to work (rls/rustfmt) you need to install the Rust sources. By default your Rust related tools will be stored in `~/.rustup`.

+`*.toml` files are used throughtout Rust developments for giving configuration (meta) information. The `Cargo.lock` file shows the cashed dependencies (you may delete the `Cargo.lock` file to force updating dependencies, `cargo clean may not be enough).

+Dependencies (may) include a minimal version, eg `itm = "0.1.1"` indicates that at least version `0.1.1` in required (so `0.1.1`, `0.1.2`, `0.2.3` is Ok, while `0.1.0` will not suffice, and a version `1.0.0` would be considered a breaking change (major number changed) and not considered. Rust follows the [semver](http://semver.org/) versioning standard.

 We encourage all sorts of collaborations in between the students. Rust is not the easiest language to learn, and we will cover a lot of ground. Use the seminars to try to get as much as possible by beig well prepared in order to succeed. We will use telegram as the main means of communictation and support from teachers as well as other fellow students, (this way information will reach everyone, keeping support as efficient as possible).
