Trait ToHexExt 

pub trait ToHexExt {
    // Required methods
    fn encode_hex(&self) -> String;

Available on crate feature alloc only.

Encoding values as hex string.

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

Examples

use const_hex::ToHexExt;

assert_eq!("Hello world!".encode_hex(), "48656c6c6f20776f726c6421");
assert_eq!("Hello world!".encode_hex_upper(), "48656C6C6F20776F726C6421");
assert_eq!("Hello world!".encode_hex_with_prefix(), "0x48656c6c6f20776f726c6421");
assert_eq!("Hello world!".encode_hex_upper_with_prefix(), "0x48656C6C6F20776F726C6421");

Required Methods

fn encode_hex(&self) -> String

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

fn encode_hex_upper(&self) -> String

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

fn encode_hex_with_prefix(&self) -> String

Encode the hex strict representing self into the result with prefix 0x. Lower case letters are used (e.g. 0xf9b4ca).

fn encode_hex_upper_with_prefix(&self) -> String

Encode the hex strict representing self into the result with prefix 0X. Upper case letters are used (e.g. 0xF9B4CA).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
