Yeah, the fact that it's hard is partly why I haven't implemented a working one one myself. :-) Regarding streaming: I don't remember exactly when I ran into this, but a text or hex editor which you also mentioned for the other use case is a clear example (e.g. if I want to search for a pattern on my disk). I would have to think back to what the actual use case I ran into myself was; it may have been this or something else... it was quite a while ago. > Is the trie data structure containing all of the file paths in memory? Well obviously not in network example (the network aspect would be moot) but there are also times when this is the case. Thanks for linking to your library! I haven't learned Rust yet but I'll take a look at it.
