macro_rules! include_bytes { ($file:expr) => { ... }; }
Includes a file as a reference to a byte array.
The file is located relative to the current file. (similarly to how modules are found)
This macro will yield an expression of type &'static [u8; N]
which is the contents of the file.
let secret_key = include_bytes!("secret-key.bin");
