Getting started
Intro
To start, open Quickstart page localhost:8020 for quick access to all the tools
From the quicklaunch page you can open workspace tools, such as code editor or terminal
The main code editor of this workspace is Code-server
Workspace has full-size browser-base terminal
Hello world
Check Rust version
rustc --version
Create new project folder
cargo new my_example
cd my_example
The new project is created together, with hello-world app in src sub-folder
cat src/main.rs
Compile it
cargo build
And then run it
./target/debug/my_example
We can also compile and then run it, all in one step
cargo run
Rustup
A toolchain is a specific version of the collection of programs needed to compile a Rust application. It includes, but is not limited to:
- The compiler, rustc
- The dependency manager and build tool, cargo
- The documentation generator, rustdoc
Rustup provides ways to install, remove, update, select and otherwise manage these toolchains and their associated pieces.
Install specific version of Rust toolchain
rustup install 1.30.0
Show toolchains
rustup show
Change default toolchain
rustup default 1.30.0
Project with dependencies
Cargo is also the Rust package manager. It is a tool that allows Rust packages to declare their various dependencies and ensure that you’ll always get a repeatable build.
Clone example repo
git clone https://github.com/rdesarz/rust-http-server.git
cd rust-http-server
Build and start the server
cd example
cargo run --package http-server --bin http-server 0.0.0.0:8030
You will see that before cargo builds the package, it installs all the dependencies from the file Cargo.toml.
Open in your browser 0.0.0.0:8030/hello.html to see a simple page.
