At long last code
The first piece of code (something relatively trivial) for finl is now on crates.io: finl-charsub is the character substitution module for finl. It may have use outside of finl when fixed character sequence replacements are needed in a text stream.
Future enhancements: I’m pretty sure that there’s room to optimize the hash map implementation that’s currently in use for building the trie. Right now, I’m using
FnvHashMap, but I have to believe that there’s a way, perhaps by eschewing Swiss Tables, to get still better performance for this use case. Since I’ll likely be implementing at least one more trie in the code (if I remember correctly, the TeX hyphenation algorithm, which I plan to shamelessly steal also uses a trie internally), there will be a chance to return to this for future optimization of the code.
