This folder contains the static arrays and lookup tables included throughout the code. 

- [`code_map.bin`](code_map.bin): a mapping from letter indices (`a` having index 0) to an internal code representing transitions in [crawdad's trie](https://docs.rs/crawdad/). 
- [`dart_base.bin`](dart_base.bin): [double-array trie](https://www.linux.thai.net/~thep/datrie/) base array generated by [crawdad](https://docs.rs/crawdad/). 
- [`dart_check.bin`](dart_check.bin): [double-array trie](https://www.linux.thai.net/~thep/datrie/) check array generated by [crawdad](https://docs.rs/crawdad/). 
- [`entropy.txt`](entropy.txt): table of all 8-bit values in a random order. Used to increase apparent entropy in input data. 
- [`syllables.txt`](syllables.txt): all 256 syllables used when encoding data.
