Initial Event Loop Run

[DasLixou]

I have a value that is taken by a function and is not Clone, and i need to call that function on init together with the event loop window target. Now there is Event::NewEvents(StartCause::Init) but that could theoretically be called multiple times so the rust analyzer errors.
Could we have another impl FnOnce as a parameter that is called on the beginning?

This is being worked on, see #3073.

Last Update was 4 months ago, any reason this is blocked?

Previously, mostly man-hours and motivation, although also that the desired design wasn't properly fleshed out.

Currently there's talk on Matrix about rewriting certain things in Winit, so that's also somewhat blocking progress here (I know that's a terrible answer, but that is roughly the status quo).

Anyhow, am gonna close this as a duplicate of #2903, let the discussion continue there.
