'error while setting conditional value in rust using format in string

I have an issue related to conditional value to a string in rust, if I remove format() everything runs fine but I have no idea how to implement this with format.

 let value =
                    if matcha.sugar {
                        format!("Hello {} your matcha is ready at {}ºC with sugar", self.client, matcha.temp);
                    }
                    else {
                        format!("Hello {} your matcha is ready at {}ºC without sugar", self.client, matcha.temp);
                    }.to_string();

Error Message:

    ]
}]

Trailing semicolons make expressions evaluate to () You need to remove the ; after the format!(...)s Also, the to_string() is useless because format!(...) already give you Strings, you would just allocate a new one for nothing
