Rust is a systems programming language sponsored by Mozilla Research. It is designed to be a "safe, concurrent, practical language", supporting functional and imperative-procedural paradigms. Rust is syntactically similar to C++, but is designed for better memory safety while maintaining performance. > [wikipedia.org/wiki/Rust_(programming_language)](https://en.wikipedia.org/wiki/Rust_%28programming_language%29)  # How to use this image ## Start a Rust instance running your app The most straightforward way to use this image is to use a Rust container as both the build and runtime environment. In your `Dockerfile`, writing something along the lines of the following will compile and run your project: ```dockerfile FROM rust:1.19.0 WORKDIR /usr/src/myapp COPY . . RUN cargo install CMD ["myapp"] ``` Then, build and run the Docker image: ```console $ docker build -t my-rust-app . $ docker run -it --rm --name my-running-app my-rust-app ``` ## Compile your app inside the Docker container There may be occasions where it is not appropriate to run your app inside a container. To compiler, but not run your app inside the Docker instance, you can write something like: ```console $ docker run --rm --user "$(id -u)":"$(id -g)" -v "$PWD":/usr/src/myapp -w /usr/src/myapp rust:1.19.0 cargo build --release ``` This will add your current directory, as a volume, to the container, set the working directory to the volume, and run the command `cargo build --release`. This tells Cargo, Rust's build system, to compile the crate in `myapp` and output the executable to `target/release/myapp`. # License View [license information](https://www.rust-lang.org/en-US/legal.html) for the software contained in this image.
