julia - Implementation of ComplexInt16 type - Stack Overflow

I have a large binary file with interleaved Int16 values representing the real and imaginary parts of each sample. Letting S_i represent the sample number i, the data is arranged as

[Re(S_1), Im(S_1), Re(S_2), Im(S_2), ...]

My thought was to define a custom ComplexInt16 type and operate on that. I produced the code below:

struct ComplexInt16
    re::Int16
    im::Int16
end

filehandle = open("y_baseband.dat")
dh = mmap(filehandle, Vector{ComplexInt16})

The code above functions as expected, but I am unable to use functions that are defined for complex numbers (e.g. real(dh[1]) returns an error.) Is there a way to have my ComplexInt16 type work with the existing Complex functions within Julia?

why not just use Complex{Int16}?
