[−][src]Trait hex::FromHex
Types that can be decoded from a hex string.
This trait is implemented for Vec<u8> and small u8-arrays.
Example
use hex::FromHex; match Vec::from_hex("48656c6c6f20776f726c6421") { Ok(vec) => { for b in vec { println!("{}", b as char); } } Err(e) => { // Deal with the error ... } }
Associated Types
type Error
Required methods
fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>
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).
