Hi, all. I am new to Julia, is it possible to build a function in struct, and whether it is efficient in coding comparing with an independent function? struct s a function f(x,a) return a*x end end

Sure, it’s valid to put almost any code in the body of struct. The body seems to act as if it was within a let, that is, it’s a local scope. So whatever you define in the body will not be available outside by default. It’s possible to override this using a global declaration.

Thanks, may I ask which one is better? (function in struct or outside struct)
