(off-topic alert)

Don't let this sound patronizing because it's not -- but have you looked at how many times is the boundary between the BEAM and the Rust code crossed? I haven't inspected Meeseks' code so can't talk, just wildly guessing.

My ancient experience with Java <-> C++ bridges has taught me that if your higher-level language calls the lower-level language very often then the gains of using the lower-level language almost disappear due to the high overhead of constantly serializing data back and forth.

Anyhow, we should probably take this discussion to ElixirForum and not here. :)

(I am @dimitarvp there and almost everywhere else on the net, HN is one of the very few exceptions of inconsistent username for me).
