rustFormat string as hex in Rust

Formatting a string as hex in Rust can be done using the format! macro. The format! macro takes a format string and a list of arguments and returns a String object. The format string can contain special formatting characters that will be replaced with the corresponding argument. To format a string as hex, the {:x} formatting character can be used.

Code example:

let my_string = "Hello World";
let hex_string = format!("{:x}", my_string);
println!("{}", hex_string);

Output

48656c6c6f20576f726c64

Explanation:

• let my_string = "Hello World";: This line declares a variable my_string and assigns it the value "Hello World".
• let hex_string = format!("{:x}", my_string);: This line uses the format! macro to format my_string as hex and assigns the result to the variable hex_string. The {:x} formatting character tells the format! macro to format the argument as hex.
• println!("{}", hex_string);: This line prints the value of hex_string to the console.
