By default, Rust treats the fields of a struct as private. However, it does not dogmatically enforce this encapsulation; we can easily opt to make fields public. In my experience, strict encapsulation is not always the optimal choice. For localized and well-defined use cases, relaxing encapsulation can significantly enhance code readability and even runtime performance. This serves as a vital reminder that architectural conventions are not silver bullets. As developers, our priority should be leveraging language features to solve real-world problems, even if doing so occasionally deviates from traditional programming dogmas.
Insight: Rust is a multi-paradigm language. Avoid getting trapped by conventions that clearly do not fit every practical engineering scenario.
