I have a vector struct, Vector(T, uint N) templated on the type T
and number of components, N. I'm trying to write a function
"cross" which will calculate the cross product of a number of
vectors.
For a given number of components, N, the cross function should
take N-1 arguments, each one a Vector!(?, N) and will return a
vector perpendicular to the vectors passed in. The ? means the
type is free to be anything.
The problem is that however I try to write it, the template
argument deduction isn't powerful enough to work out which
instantiation to use.
I thought something like this would work to deduce the parameters
and then I could use constraints to enforce the other rules, but
no:
auto cross(T, N, U...)(Vector!(T, N) a, U b) { return 0; }
