Object-oriented design patterns in Rust
Introduction to patterns in Rust
While Rust isn’t traditionally OOP, many common software design patterns can be effectively implemented by leveraging traits, enums, and composition. What makes this particularly powerful is how Rust’s core features often lead to more robust and type-safe versions of these patterns than in other languages.
For example, Rust’s expressive enums are perfect for creating compile-time verified state machines (the State pattern), while the ownership system provides a natural and safe way to manage resource construction (the Builder pattern).
The borrow checker adds another layer of safety, preventing invalid state mutations at compile time. This means you can implement familiar patterns with a higher degree of confidence in their correctness.
Builder pattern
The Builder pattern is useful when constructing an object with many fields, especially if many are optional or require...
