How does this interoperate with the Rust program it's embedded in? Is making functions or values available to it as tedious and verbose as in Lua? Or is there some way of calling Rust functions or accessing Rust values automatically from inside embed_lang neé Gluon? I'm assuming it's just as tedious as in Lua, since otherwise it would need powerful runtime reflection, which seems like a feature that Rust wouldn't really have or want.

Lua has one of the cleanest no_magic c-apis of any scripting language. LuaJIT has the cleanest with_magic c-apis of any scripting language. So clean that it has been copied by PyPy [0], Guile [1] and others.

And yes, Gluon appears have to an extremely low friction interface to Rust. See my comment above.

  What do you mean by magic here?

    Magic in the LuaJIT sense is automatically parsing C declarations and constructing shims from LuaJIT into native code without having to interact with a C compiler.
