Trait hex::FromHex [−][src]
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!"

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).
