matovitch:
struct Test
{
immutable (ubyte)[] data;
T get(T)()
{
return *(cast(T*)(&(data[0])));
}
It's better to return const/immutable data. Otherwise the program
gives undefined results. In alternative use mutable ubytes for
data.
Also &data[0] is probably data.ptr.
This won't compile :
import std.stdio;
void main()
{
Test t;
t.data = [152, 32, 64, 28, 95];
float b = t.get;
writefln("%s", b);
D doesn't perform inference on the return type.
This neither:
...
Test t;
t.data = [152, 32, 64, 28, 95];
float b = t.get!(typeof(b));
writefln("%s", b);
I don't know. Perhaps b is not yet defined. This in theory could
work.
In fact this would allow a nicer syntax for the Json struct in
vibe.d for example.
I don't think in future D will behave differently on this code.
