There was a Google Summer of Code project in 2015 doing a UNO Haskell 
binding.  See 
<https://wiki.documentfoundation.org/index.php?title=Development/GSoC/Ideas&oldid=121170#Haskell_UNO_Language_Binding> 
for high-level code pointers.  See 
<https://github.com/jorgecunhamendes/haskell-uno-binding> for the 
results (though still quite rough).

There is still an open GSoC project for a UNO Rust binding,

Not that I know of.
