Requests vs. Notifications

[KillTheMule]

From the Roadmap:

Consider making a difference between requests and notifications, and send out notifications with the proper message type, and don't wait for a response

Does neovim actually recognize this? Read the docs! Maybe everything's a requests anyways, then don't bother
It does, see https://neovim.io/doc/user/api.html#api-global-events. Maybe not so usefull since there seems little to do where you don't want direct error feedback

So we could send out requests without a real return value, such as nvim_buf_set_lines, as notifications instead.

• Pros:
  • This would save a bit of RPC traffic, as we don't get an answer unless there was an error
• Cons:
  • Need to implement handling the error event
    • Needs design work: Always handle? Let clients handle it on their leisure?
    • Makes everything more complicated
  • Gets us into trouble because of timing issues, we don't know exactly which message the error event belongs to.

My take: It's not worth it.
