Hi,
I have an anoying situation where I want to copy a variable of composed type by changing a value of the field which may in turn change the type. Here is an example
# in my application, the following struct contains ~20 fields...
struct A{T,vectype}
p::T
v::vectype
end
a = A(Int32(1), rand(10))
is of type A{Int32,Array{Float64,1}}
. What I would like to do is something like this
b = copy(a, p = 0.21)
I face two issues. The first is I want to change an element, so writing this is anoying
b = A(p = 0.21, v = a.v) # I would have to write every field :frowning:
I cant do
b = deepcopy(a)
b.p = 0.21
as the types dont match.
Does anybody have a solution please?
Thank you,
