Imperator Save

Imperator Save is a library to ergonomically work with Imperator Rome saves (debug + standard).

use imperator_save::{ImperatorExtractor, Encoding};
use std::io::Cursor;

let data = std::fs::read("assets/saves/observer1.5.rome")?;
let reader = Cursor::new(&data[..]);
let (save, encoding) = ImperatorExtractor::extract_save(reader)?;
assert_eq!(encoding, Encoding::Standard);
assert_eq!(save.header.version, String::from("1.5.3"));

ImperatorExtractor will deserialize standard Imperator saves as well as those saved saved with -debug_mode (plaintext).


By default, standard saves will not be decoded properly.

To enable support, one must supply an environment variable (IMPERATOR_TOKENS) that points to a newline delimited text file of token descriptions. For instance:

0xffff my_test_token
0xeeee my_test_token2

In order to comply with legal restrictions, I cannot share the list of tokens. I am also restricted from divulging how the list of tokens can be derived.
