rustHow do I insert a variable into a string in Rust?

You can insert a variable into a string in Rust using the format! macro. This macro allows you to insert variables into a string using the {} placeholder. For example:

let name = "John";
let message = format!("Hello, {}!", name);

This will output Hello, John!.

The format! macro takes the following parts:

• format!: The macro itself.
• "Hello, {}!": The string with the {} placeholder.
• name: The variable to be inserted into the string.

For more information, see the Rust documentation.
