rustHow to convert Rust bytes to hex?

To convert Rust bytes to hex, you can use the format! macro. This macro takes a format string and a list of arguments, and returns a String containing the formatted output. The format string {:x} will format the argument as a hexadecimal number.

let bytes = vec![0x41, 0x42, 0x43];
let hex_string = format!("{:x}", bytes);
println!("{}", hex_string);

Output example

414243

The code above does the following:

1. Creates a vector of bytes (vec![0x41, 0x42, 0x43])
2. Uses the format! macro to format the bytes as a hexadecimal number ({:x})
3. Prints the resulting hexadecimal string (414243)
