V: what is the address of struct ?

[k1attila12]

V version:
OS: win10

What did you do?

struct Mo {mut: x int}

fn main() {

mut w:=Mo{1}

println(&w) //this doesn't work
println(&(w.x)) //this work
}

What did you expect to see?
the address of w

What did you see instead?

[danieldaeschle]

the second example shows you the address of x. but it shouldn't. We won't print addresses. the first println is correct but a missing & in front.

[k1attila12]

Hi
I don't understand.
The second println OK, because it print the address of w.x
The first one doesn't print the adress of w.

[danieldaeschle]

it should never print the address imo

[k1attila12]

I know
I think it should print : &{1} //in Go it is the result

but in V : Mo{ x:1 }

Is it OK ?

[danieldaeschle]

yep, see https://github.com/vlang/v/issues/6743

Why should V not print addresses? That makes cave man debugging much harder.

@medvednikov should decide

You can print voidptr addresses:

println(voidptr(&w)) // 13fe8c

OK. Thank you Sir.

println(voidptr(&w)) // 13fe8c

will this be the official way to print addresses?

There is a builtin ptr_str function, that (afaik) does the same thing but is more explicit:

println(ptr_str(&w)) // 7ffee5210888
