Specifying type of interpolated image in a struct

General Usage
1

I have a struct

struct some_struct{}
    interpolated_img
end

where I want to store an interpolation ‘image’. When I print the typeof() such an image, I get Interpolations.BSplineInterpolation{Gray{Float64}, 2, Matrix{Gray{Float64}}, BSpline{Linear{Throw{OnGrid}}}, Tuple{Base.OneTo{Int64}, Base.OneTo{Int64}}} .

If I don’t specify any type, it assumes it as Any, but if I want to specify the type should I specify it as something like
interpolated_img::Interpolations.BSplineInterpolation{Gray{Float64}, 2, Matrix{Gray{Float64}}, BSpline{Linear{Throw{OnGrid}}}, Tuple{Base.OneTo{Int64}, Base.OneTo{Int64}}}
or is there some better way to do this?

You can add a type parameter that will be filled in when compiled.

struct some_struct{T}
    interpolated_img::T
end

Perfect, thank you!
