Hi!
I'm sorry,maybe this topic already was discussed,but could
anybody explain me
why default constructor was disallowed in structs?
And if I have to do some initialization of data members,what is
the way to do it?
TDPL, the book by Andrei Alexandrescu, says that it was done for
having compile time known default value for structure types which
is T.init in general. For classes T.init is null so there is no
problem. Assumption here is that statically known T.init and
default constructor cannot coexist, however there are discussion
in this forum that this issue may be reconsidered.
Absence of default structure constructors is a piece of the
puzzle which is creation of D structures and consists of
structure constructors, static/object opCall methods, struct
literals together with static initialization. You may use any of
this method for initialization, the problem is IMHO in their
contradiction and priority.
