Rust and Default ParametersRust doesn’t support default parameters in function signatures. And unlike in many languages, there’s no way to simulate them with function overloading. This is frustrating for many new Rustaceans coming from other programming languages, so I want to explain why this is actually a good thing, and how to use the Default trait and struct update syntax to achieve similar results.
Default parameters (and function overloading) are not part of object-oriented programming, but they are a common feature of a lot of the programming languages new Rustaceans are coming from.
