Chunks type function for potential data parallelism
Is it possible to get an iterator like the chunks iterator because I'm trying to write code to parallel manipulate the image using crossbeam::scope threads? However, I can't convince the compiler that I'm operating over non overlapping regions of the image when I split it up into sub images. Chunks used in Vec
If the implementor of GenericImage is allowed to choose the chunk size, then maybe it is possible to work around the language level issues discussed in #888. For some images, the intended solution for ffi FlatSamples could help you out. Create it by ImageBuffer::as_flat_samples etc.
Thank you. Would it be possible to have a chunks like iterator for the flat samples?
Also what would I have to look into to let GenericImage choose the chunk size? I'm new to this so I don't know where to start.
Possibly, but we can not introduce a hard dependency on rayon due to the wasm target as far as I am aware. So only behind a non-default feature flag or some other switch.
As far as I understand when https://github.com/rayon-rs/rayon/pull/636 lands, wasm support in rayon should be right around the corner. Until then having some sort of rayon support behind a feature gate would be nice.

Note that parallelisation in Wasm is supported nowadays and we recently published an adapter for Rayon + Wasm: https://github.com/RReverser/wasm-bindgen-rayon
Incidentally, even though I wrote that adapter for work & OSS, I now need it in side project where I'm dealing with images and was hoping to parallelise some image operations as well - that's how I found this issue :)
