[erlang-questions] Trie NIFs

I'm looking for a trie NIF library that can support strings as trie
tokens, and basic pattern matching with a '.' like wildcard (i.e. If /
is the trie separator and the tree contains 3 entries: /usr/bin,
/usr/include/X12/XTrans, /usr/include/X11/Xtrans, then I can do

trie:get_all(["usr", "include", '.', "XTrans"])

and it will return

[["usr","include","X11","Xtrans"],
 ["usr","include","X12","Xtrans"]]

It would also be nice to have a

trie:get_single(["usr","include", '.', "XTrans"])

that returns only one of the matching entries

Does anyone know of such a NIF library? Or something similar enough
that I can modify it for these needs?

Regards, OriB.
