This recipe shows how to build an offchain-worker that the runtime communicates with asynchronously by issuing events with callbacks the offchain worker responds to at a later point.
Note: expects to have a full substrate checkout in ../substrate to work.
cargo run --release -- --devsee docs/index.html (or rendered here on github pages: https://gnunicorn.github.io/substrate-offchain-cb/ ) for a nicely rendered html of the inline docs explaining the runtime code.
