This post delves into dynamic dispatch in the Rust programming language, with comments expressing optimism about future features like erased types and existential types that could enhance the functionality of Rust's type system. The desire for these features suggests a push towards creating type-safe APIs compatible with object-oriented programming (OOP) concepts, despite Rust's aim to avoid multiple inheritance issues commonly associated with OOP, specifically the diamond problem. Additionally, the comments highlight a preference for composition over inheritance, aligning with Rust’s design philosophy.
