Trait Parameter

Define a trait Describe with a method describe(&self) -> String. Implement it for Planet (with a name: String field). Write a function print_info that takes &impl Describe and prints the description. Test it with planet "Mars".

Expected output:

Planet: Mars

Hints:

• fn print_info(item: &impl Describe) accepts any type with Describe
• The describe method should return format!("Planet: {}", self.name)
