rustFormat string escape character in Rust

In Rust, the escape character for formatting strings is the backslash (\). This character is used to escape certain characters in a string, such as quotation marks, newlines, and other special characters. For example, the following code will print out the string "Hello, World!":

let my_string = "Hello, World!";
println!("{}", my_string);

Output

Hello, World!

The backslash character is also used to insert special characters into a string, such as a newline character. For example, the following code will print out the string "Hello,

World!":

let my_string = "Hello,\nWorld!";
println!("{}", my_string);

Output

Hello, World!

Explanation of code parts:

1. let my_string = "Hello, World!"; - This line declares a variable called my_string and assigns it the value of the string "Hello, World!".

2. println!("{}", my_string); - This line uses the println! macro to print out the value of the my_string variable. The {} is a placeholder for the value of the my_string variable.

3. let my_string = "Hello,\nWorld!"; - This line declares a variable called my_string and assigns it the value of the string "Hello,\nWorld!". The \n is an escape character that represents a newline character.

4. println!("{}", my_string); - This line uses the println! macro to print out the value of the my_string variable. The {} is a placeholder for the value of the my_string variable.
