[go-nuts] Re: slice of pointer of struct vs slice of struct
hmm, suppose I have struct X that have 50 attributes that represent 50 cols
in db, struct Y 4 attributes, 4 cols
and I have :
func FindX() *X {}
func FindXs() []*X {}
func FindY() *Y {}
func FindYs() []*Y {}
I don't care about mutable, since this is only a getter func, or should I
care?
since I already queried to db, and the caller is free to do anything to
that result
because X is large, then I prefer pointer,
and then for the sake of consistency,
others (e.g. struct Y) I set them too as pointer,
regardless other structs may be a small struct
no receiver func yet for those structs
no modifying, mostly just reading the result

[go-nuts] Re: slice of pointer of struct vs slice of struct
so if I have like 50 attributes then pointer is preferable then
How big is big? I took
from https://github.com/golang/go/wiki/CodeReviewComments for receiver, is
this applicable for this too?
Assume it's equivalent to passing all its elements as arguments to the
> method. If that feels too large, it's also too large for the receiver.

[go-nuts] slice of pointer of struct vs slice of struct
Hi,
I got vague answers in the internet over this.
Which is better & preferable in Go?
type T struct {
// some attributes
...
}
func a() []T {
}
func b() []*T {
}
Thanks
