Implement the Simple Rust Default Trait 🦀 Rust Tutorial for Developers

The Rust standard library provides a "default" module, which declares a trait named "Default." This trait provides a single, simple method declaration called "default()" that you can implement on your custom Rust structs. The purpose of this default() function is to simplify the construction of new Rust struct instances. Normally you'd need to specify every single data field, when instantiating your structs. With default(), you can configure some "sane" default values in a standardized way that Rust's primitive types also use (ie. i32, u16, String, etc.).

Thanks, awesome feature and great explanation!

Thanks for the video. I am however a bit confused by your use of the term "wrap" in the video. Aren't you just using a tuple struct with a single element of type String and implementing the Default trait for it and using that new data type as a named field inside your Person struct?
Also. That changes the semantics of how you can access the value of the first name string elsewhere in the code.

Thanks for you work. Makes it easier to go through Rust learning journey. Would you be able to make video that explains things like Rc, Arc, Box, Cell, Field, Pin etc. please?

First of all, Great videos Thank you for all rust related videos. I need some help in event handling in Rust. Kind of a implementation like, register a callback, whenever there is a event fireevent occurs all the registered callback gets called. How can I implement them in Rust?
