const IO_ERR_MESSAGE: &str = "\
An I/O error happened. Please make sure you can access the file.

By default, if your project contains a build script, cargo scans all files in
it to determine whether a rebuild is needed. If you don't expect to access the 
file, specify `rerun-if-changed` in your build script.
See https://doc.rust-lang.org/cargo/reference/build-scripts.html#rerun-if-changed for more information.";
