Suppose I have a container, a, could be a Tuple, a Vector, or a user-defined subtype of AbstractArray. Now I want to convert every element of a to another type, e.g., from Ints to Float64. For example, I write a rough function: convert_eltype(T::Type, a) = map(x -> convert(T, x), a) This function …

This is basically the same question you asked in How to get the container type of a container? . You’ll have to define a similar_type overload for each concrete FieldVector subtype you define. If that’s too much of a hassle, you could write a macro to generate the similar_type method along with the F…
