I spent the weekday mostly working and doing other things so I try to spend a couple hours every weekend doing more rustling challenges as it still seems thats getting me to understand the basics of rust better. After I finish rustlings I will go back to looking at bevy. Maybe it will look less cryptic.

Structs hold a bunch of values like tuples. But a struct will have each piece of data named ie: key:value pairs. Structs are pretty powerful as there are no Classes in rust. Structs are used to make “Classes”

struct Duck{
 awesomeness:f32, //Basic values
 name:(String), 
 color:(u8,u8,u8), //Tuples can be stored
 //I DONT THING YOU CAN NEST ENUMS..... lmk bois
}

To use a struct, you can access bits of it using the dot notation.

let dave = Duck{
  awesomeness:100.0,
  name: String::from("Dave"),
  color:(255,255,0),
};
println!("{}",dave.name);

We (yes, both you and I) can make a new struct that has all the same values as another instance of a struct and then change whatever you want.

//Given the duck struct above and its instance of dave
let david = {
 name: String::from("Daveed"),
 ..dave
}

david is the same as dave except for his name! ¹⁾

Structs can also have functions attached to it. using impl.

impl Duck{
 fn print_name(){
 println!("{}",self.name);
 }
}

this is how you can make a class with structs. The Declaration of the struct is like a C++ header file and the impl like the cpp file ²⁾.
