# 1.0.0[−][src]Macro core::include_str

    macro_rules! include_str {
        ($file:expr) => { ... };
        ($file:expr,) => { ... };
    }

Includes a utf8-encoded file as a string.

The file is located relative to the current file. (similarly to how modules are found)

This macro will yield an expression of type `&'static str` 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 my_str = include_str!("spanish.in");
        assert_eq!(my_str, "adiós\n");
        print!("{}", my_str);
    }

Run

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