rustHow do I convert a hex string to bytes in Rust?

To convert a hex string to bytes in Rust, you can use the from_hex method from the hex crate. This method takes a &str and returns a Result<Vec<u8>, hex::FromHexError>.

Example code

use hex;

let hex_string = "deadbeef";
let bytes = hex::from_hex(hex_string).unwrap();

Output example

[222, 173, 190, 239]

Code explanation

• use hex;: imports the hex crate
• let hex_string = "deadbeef";: creates a &str with the hex string
• let bytes = hex::from_hex(hex_string).unwrap();: calls the from_hex method from the hex crate, passing the &str as an argument, and unwraps the Result
