if the 'T' is a struct, it will not exec the Destory
function. Is it a bug?
What do you mean? This works for me:
---
import std.stdio, std.typecons;
struct Foo {
~this() {
writeln("I'm destroyed");
}
}
void main() {
Unique!Foo foo = new Foo;
} // Prints "I'm destroyed"
---
the "writeln("I'm destroyed");" not run the ~this in the Unique
destroy function.
it run in the app exit , THe GC distroy all memony.
it example can show :
import std.stdio;
import std.typecons;
struct Foo {
~this() {
writeln("I'm destroyed");
}
}
void fun(){
Unique!Foo foo = new Foo;
writeln("exit the fun.");
}
void main() {
fun();
writeln("exit the Main.");
}
It is the printf:
~/tmp rdmd ./type.d
2017年01月16日 星期一 09时50分00秒
exit the fun.
exit the Main.
I'm destroyed
~/tmp
if you use the struct in Unique, the struct's Destory function is
not run in the Unique destroy, it is also run in the GC collet.
I think it is not the Unique should be.
