Summary

With Rust, we have seen that there are some traps when coming from a dynamic programming language background. However, with a little bit of knowledge of referencing and basic memory management, we can avoid common pitfalls and write safe, performant code quickly that can handle errors. By utilizing structs and traits, we can build objects that are analogous to classes in standard dynamic programming languages. On top of this, the traits enabled us to build mixin-like functionality. This not only enables us to slot in functionality when it’s useful to us but also perform checks on the structs through typing to ensure that the container or function is processing structs with certain attributes belonging to the trait that we can utilize in the code.

With our fully functioning structs, we bolted on even more functionality with macros and looked under the hood of basic macros by building our own capitalize function, giving us guidance for further reading and debugging...
