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!"Required Associated Types§

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
