pub trait FromHex: Sized {
type Error;
// Required method
fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>;
}Expand description
Types that can be decoded from a hex string.
This trait is implemented for Vec<u8> and small u8-arrays.
Example
use core::str;
use hex::FromHex;
let buffer = <[u8; 12]>::from_hex("48656c6c6f20776f726c6421")?;
let string = str::from_utf8(&buffer).expect("invalid buffer length");
println!("{}", string); // prints "Hello world!"
