Macro std::include_str

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

Includes a UTF-8 encoded file as a string.

The file is located relative to the current file (similarly to how modules are found). The provided path is interpreted in a platform-specific way at compile time. So, for instance, an invocation with a Windows path containing backslashes \ would not compile correctly on Unix.

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':

fn main() {
    let my_str = include_str!("spanish.in");
    assert_eq!(my_str, "adiós\n");
    print!("{}", my_str);
}

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