Macro include_str

macro_rules! include_str {
    ($file:expr $(,)?) => { ... };
}
šŸ”¬This is a nightly-only experimental API. (prelude_2024)
Expand description

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.

Ā§Examples

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

File ā€˜spanish.inā€™:

adiĆ³s

File ā€˜main.rsā€™:

ā“˜
fn main() {
    let my_str = include_str!("spanish.in");
    assert_eq!(my_str, "adiĆ³s\n");
    print!("{my_str}");
}

Compiling ā€˜main.rsā€™ and running the resulting binary will print ā€œadiĆ³sā€.
