Trait hex::FromHex[][src]

pub trait FromHex: Sized {
    type Error;
    fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>;
}

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!"

Required methods

fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>[src]

Creates an instance of type Self from the given hex string, or fails with a custom error type.

Both, upper and lower case characters are valid and can even be mixed (e.g. f9b4ca, F9B4CA and f9B4Ca are all valid strings).
