Trait ToHex

pub trait ToHex {
    // Required methods
    fn encode_hex<T: FromIterator<char>>(&self) -> T;
    fn encode_hex_upper<T: FromIterator<char>>(&self) -> T;
}

Encoding values as hex string.

This trait is implemented for all T which implement AsRef<[u8]>. This includes String, str, Vec<u8> and [u8].

Example

use hex::ToHex;

println!("{}", "Hello world!".encode_hex::<String>());

Note: instead of using this trait, you might want to use encode().

Required Methods

fn encode_hex<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Lower case letters are used (e.g. f9b4ca)

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Upper case letters are used (e.g. F9B4CA)

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.
