Secure Rust development with GitLab

This post details how to integrate Rust development workflows into GitLab CI/CD. It provides specific `.gitlab-ci.yml` configurations for building Rust applications across multiple platforms (Linux, Windows, macOS) using cross-compilation, setting up automated unit and integration tests, running linters (Clippy) and formatters, and publishing packaged artifacts (tar archives) and container images to GitLab's Package and Container Registries. It highlights the use of caching for Rust dependencies and compiled artifacts to speed up build times.
