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 thehex
cratelet hex_string = "deadbeef";
: creates a&str
with the hex stringlet bytes = hex::from_hex(hex_string).unwrap();
: calls thefrom_hex
method from thehex
crate, passing the&str
as an argument, and unwraps theResult
