When developing programs, we have to solve many problems. A program can be viewed as a solution to a problem. It can also be viewed as a collection of solutions to many problems. All of these solutions work together to solve a bigger problem.
There are many problems that share the same form. Due to the fact that Rust is not object-oriented, design patterns vary with respect to other object-oriented programming languages. While the details are different, since they have the same form they can be solved using the same fundamental methods:
- Design patterns are methods to solve common problems when writing software.
- Anti-patterns are methods to solve these same common problems. However, while design patterns give us benefits, anti-patterns create more problems.
- Idioms are guidelines to follow when coding. They are social norms of the community. You can break them, but if you do you should have a good reason for it.
TODO: Mention why Rust is a bit special - functional elements, type system, borrow checker
