spent the last couple of days taking the foundations of rendering and windowing code for my engine, swapping out winit and putting in sdl2 in place of it. takes a bit of a fight, but I eventually figure it all out.
found out resizing the window doesn't update the contents of the window continuously, something winit let me do practically out of the box. looks stupid. want it fixed.
spend many hours poring through documentation, working with one of my partners to help figure out what I'm missing in Rust code in general. several fights with the borrow checker, construction of part of a new event loop system running alongside sdl2's event pump. run the code, and... it still blocks on resizing the window or dragging it around on screen. because I tried to put the code for actually fixing the surface size and rendering it in the normal event loop, after the event queue ends, not realizing that it wasn't holding the events until the window drag ended, it was blocking execution on that thread entirely.
search around, finding out that this is just how sdl2 has been for over a decade, and the only workaround would be to finish making an alternative event loop that I was trying not to do, and flush the event queue regularly to make sure it doesn't get overflowed. which sounds like an absolute pain. before November of last year, it wouldn't even have been possible, without going into OS native APIs.
... sdl2 has outstayed its welcome. I'm putting winit back in my project.
