Main goal of this workspace is educational. It describes a way how to replicate cross-platrform Rust library with C++ dependency for all major mobile and desktop OS in a testable manner. Rust libping wrapper library is linted, built and tested automatically for Linux/Windows/macOS/iOS/Android on each PR both with unit and integration tests. For mobile testing mobile simulators are used. C++ code compilation, FFI and linking issues are addressed. For the CI test pipeline see rust.yml
