rustHow to uppercase enum in Rust

To uppercase an enum in Rust, you can use the to_uppercase() method on the enum's Variant type. For example, if you have an enum called MyEnum with variants Variant1 and Variant2, you can uppercase them like this:

let my_enum = MyEnum::Variant1;
let uppercase_enum = my_enum.variant().to_uppercase();

This will set uppercase_enum to VARIANT1.

The to_uppercase() method is part of the std::string::ToString trait, which is implemented for all Variant types. This means that you can use to_uppercase() on any enum variant.

Example ### Output

uppercase_enum = VARIANT1

Explanation

The let my_enum = MyEnum::Variant1; line creates a new MyEnum enum with the Variant1 variant. The let uppercase_enum = my_enum.variant().to_uppercase(); line then calls the to_uppercase() method on the Variant1 variant, which returns the uppercase version of the variant.
