I am working on a Docker container and getting 'can't find rust compiler'. How can I resolve it?

When working in a Docker container, the Rust compiler (rustc) and Cargo need to be installed inside the container's image. You'll typically use a Dockerfile with instructions like `RUN apt-get update && apt-get install -y --no-install-recommends rustc cargo` (for Debian/Ubuntu) or similar commands for other distributions. Ensure these commands are included in your Dockerfile before you build your project.
