# 1.0.0[−][src]Macro std::include_bytes

    macro_rules! include_bytes {
        ($ file : expr) => { ... };
        ($ 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':

ⓘThis example is not tested

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

Run

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