Hiya,
Here's an proposal for some abi-stable equivalents of the Fn traits, to allow passing closures over the FFI boundary easily.
I'm planning on proposing something similar for
std::future::Future
soon (working on theWaker
at the moment).Let me know if you'd like to see some changes. Note that I only handled the single argument case, under the judgement call that if you want to pass multiple parameters to a closure over FFI, you might want to make sure the layout of the passed value suits you.
