Fix Generic Struct
This code defines a generic Container with a show method, but the impl block is missing its generic parameter! Fix it.
Fix the code so it prints:
Contains: 42
Hint: The impl block needs <T: std::fmt::Display> to match the struct.
rust
struct Container<T> {
item: T,
}
impl Container {
fn show(&self) {
println!("Contains: {}", self.item);
}
}
fn main() {
let c = Container { item: 42 };
c.show();
}
