rust enum to string

To convert an enum to a string in Rust, you can use the ToString trait. Here's an example:

enum MyEnum {
    Variant1,
    Variant2,
    Variant3,
}

impl ToString for MyEnum {
    fn to_string(&self) -> String {
        match self {
            MyEnum::Variant1 => String::from("Variant1"),
            MyEnum::Variant2 => String::from("Variant2"),
            MyEnum::Variant3 => String::from("Variant3"),
        }
    }
}

fn main() {
    let my_enum = MyEnum::Variant1;
    let enum_string = my_enum.to_string();
    println!("{}", enum_string);
}

In this example, the ToString trait is implemented for the MyEnum enum. The to_string method is defined to return a String representation of each variant of the enum. You can customize the string representation for each variant as needed.

Please note that the ToString trait is part of the Rust standard library, so you don't need to import any additional crates to use it.

I hope this helps! Let me know if you have any further questions.
