Scalar indexing can occur on `show` for arrays of DiskArray about diskarrays.jl

Ahh no, this is when the generic method is used on a wrapper array type.

It's annoying that we have to handle this in all wrappers by explicitly forwarding show.

[meggart]

Yes, I find this annoying as well indeed. I have no idea how to solve this though as long as there are no Array traits that are accepted by show for Abstract Arrays in Julia Base. Do you happen to know how the gpu people are solving this when dealing e.g. with CuArrays? They should have pretty slow random access as well (but probably not as slow as compressed arrays on disk/in the cloud).

[rafaqz]

Yeah we should look at what CuArrays do. Since they have allowscalar too they would have to avoid that error somehow on show?

Thats how I found this, setting DiskArrays.allowscalar(false) means show breaks if you have e.g. a vector of wrapped disk arrays.

I'll handle it in Rasters.jl by adding show without MIME and checking if the parent array is disk based. But automatically forwarding a trait to parent would be best long term, somehow or other.

Closing, not actually a DiskArrays.jl problem
