rustHow to format string with braces in Rust

String formatting in Rust is done using the format! macro. This macro allows you to insert values into a string using braces {} as placeholders.

Example:

let name = "John";
let age = 30;
println!("My name is {}, and I am {} years old.", name, age);

Output

My name is John, and I am 30 years old.

1. The format! macro is used to format strings in Rust.
2. The {} braces are used as placeholders for values that will be inserted into the string.
3. The values to be inserted into the string are passed as arguments to the format! macro.
4. The println! macro is used to print the formatted string to the console.
