arenatag. When I needed I went with typed-arena, it looks solid, though each closure has a different type (all with FnSomething traits), typed-arena or slab wouldn't do. There's also copy_arena, but I doubt closures are Copy so no good. I read on nightly docs that the unstable std::arena::Arena may get deprecated in favor of any-arena (which I haven't found a crate for). Anyway fn-arena may be a good name if that's the primary goal.
