Seems like mapview function can be used instead of SingleFieldStructArray with exact same performance. It is even more general and shorter to type :)
Eg:

# either vanilla:
mapview(x->x.t, foos)
# or even, for convenience:
mapview(:t, foos)

# instead of
SingleFieldStructArray(foos, Val{:t})

The mapview function is available in either SplitApplyCombine.jl (older, more popular) or FlexiMaps.jl (newer, more focused and featureful).

Not to discourage the package, especially in case if there are any non-trivial advantages of SingleFieldStructArray. At least I think these advantages (wrt mapview that has been around for a long time) should be highlighted in the readme.

Could you highlight what are the advantages of this package over StructArrays.jl?

@aplavin Excellent, thanks for the comment. As you might have guessed, I was unaware of both SplitApplyCombine.jl and FlexiMaps.jl's mapview. :-) FlexiMaps.mapview appears to do exactly what I want, and so I don't see any need to register this package.

@jishnub Re: SingleFieldStructArrays.jl vs StructArrays.jl, my understanding is that they do opposite things. StructArrays.jl takes a struct of Arrays and makes it look like an Array of structs. SingleFieldStructArrays.jl takes an array of structs and makes it look like an array of one of the struct elements.
