Typeclasses are Interfaces 2.0: From Java to Rust

- Typeclasses in Rust (traits) and Haskell (classes) are advanced versions of interfaces in Java.
- Java interfaces cannot express certain type relationships, such as methods returning the same type as the implementor or static methods.
- Typeclasses allow for implementation on foreign types, unlike Java where types can't implement new interfaces after definition.
- Typeclasses support type alias stubs, enabling more precise type relationships than Java's generics.
- Conditional implementation of typeclasses allows for more flexible and powerful abstractions, such as collections implementing traits only if their elements do.
