Correction: the View struct is in src/wayland/output.h, not view.h

But if I try to copy the contents of the View struct into the Client struct (src/client.h) and use the Client struct to hold data about my view instead of the View struct, so every instance of View is replaced with Client, my compositor segfaults at src/wayland/xdg_shell.c line 170 when I close the last window on the screen. (I think it was that line, I don't have the backtrace to hand.)
