pub fn load_visa_library() -> Result<(), Error>Expand description
Manually load the VISA library from the platform default path.
Returns Ok(()) if the library was loaded successfully (or was already loaded).
Returns Err if loading fails, e.g. because the library is not installed.
This is optional — calling any VISA function will auto-load the library with the default path. Use this function to detect missing libraries before the first call.
