This kind of solves #59 I'm not sure if the added test actually tests the UB but it seems to pass on my machine without panics. I'll double check it though. Update: It looks like the panic is only hit if we transmute to something which includes one of the
bevy-trait-query
component types (One
orAll
). I added an additional test which highlights this. There's also an explicit panic inbevy-trait-query
now which will guide users to the issue which causes the trouble and which provides minimal help.For performance differences, see this comment: #59 (comment) (TLDR:
All
performance improves,One
performance regresses)
