Reading byte-aligned struct from binary file

You could to something like

julia> struct Foo
         fill::Cchar
         sex::Cchar
         days::Int16
         breed::Tuple{Cchar, Cchar}
       end

julia> Base.show(io::IO, f::Foo) = print(io, Char(f.sex), ' ', f.days, ' ', Char(f.breed[1]), Char(f.breed[2]))

julia> buf = zeros(UInt8, 6);

julia> open("test.bin", "r") do io
         for i in 1:3
           read!(io, @view(buf[2:6]))
           println(i, ": ", reinterpret(Foo, buf)[1])
         end
       end
1: F 1111 JE
2: M 2222 AY
3: F 3333 HO

or even

julia> function readfile(file)
         open(file, "r") do io
           out = zeros(UInt8, 18) 
           for i in 0:2
             read!(io, @view(out[6i .+ (2:6)]))
           end
           reinterpret(Foo, out)
         end
       end
readfile (generic function with 1 method)

julia> readfile("test.bin")
3-element reinterpret(Foo, ::Vector{UInt8}):
 F 1111 JE
 M 2222 AY
 F 3333 HO
