Macro std::include_bytes

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.

Examples

Assume there are two files in the same directory with the following contents:

File 'spanish.in':

adiós

File 'main.rs':

fn main() {
    let bytes = include_bytes!("spanish.in");
    assert_eq!(bytes, b"adi\xc3\xb3s\n");
    print!("{}", String::from_utf8_lossy(bytes));
}

Compiling 'main.rs' and running the resulting binary will print "adiós".
