Macro hex_lit::hex_const

macro_rules! hex_const {
    ($name:ident = $hex:expr) => { ... };
}

Available on crate feature rust_v_1_46 only.

Creates a constant byte array of given name.

This is a convenience macro so that you don’t have to write out the type. However it is intentionally not public - public constants must be explicitly typed to avoid accidental change of the type.

Example

use hex_lit::hex_const;
// same as writing `const FOO: [u8; 2] = [0x00, 0xff];`
hex_const!(FOO = "00ff");

assert_eq!(FOO, [0, 255]);
