#if 0 looks wrong, though I know it is right. Perhaps add a comment, or standardize how we do this

Hmmm. Need to do a pass over these. Slowly switched to the simpler if 0 variant because the other thing got implemented incorrectly too often

Why? A raw pointer has the benefit of being simple and much, much faster in debug builds

Correct, but it will break down soon once we have strides

What
... and various improvements to
rerun::Collectionin general to be up for the task. Added copy assignment/construction, added vector conversion, removed serialization method (handled at callsites now)Also, I overhauled and generalized our builtin
rerun::CollectionAdaptersfurther. They give now more exact guarantees on when they copy & move data.To support the considerably increased significance and abilitites of this data structure I added a lot more tests, in particular checking on the aforementioned move/copy guarantees.
Huge thanks to @AnkeAnke for pointing out to me how we can support std compatible contains generically in a trivial way (
rerun::type_traits::value_type_t!). This made it possible that this PR requires almost no changes in user/test/example code since most types just snap in the same as before.As expected this change improves the performance on the image logging benchmark (which logs 4 16k rgba images).
Timing on M1 Max went from ~2.9s to ~2.4s and on the AMD windows box I use from ~3.0s to ~2.5s
(did a bunch of runs, values are excluding prepare and process setup, AMD fluctuates a lot)
DRAFT until I'm sure this works on more compilers.
