Posted: 07/26/07 16:40:07 I was reading through the docs to find out how to serialize a struct: struct Wombat { void read (IReader input) {...} void write (IWriter output) {...} } Wombat wombat; output (&wombat.write); input (&wombat.read); I came accross this... but I'm still not sure what i should write in the functions read/write (I'm new to D too) Cheers for any help ;) Raedwulf

In particular, read() should ensure the aggregate is in a usable state where there are some fields that are not persisted. Classes are generally simpler to apply, because they support interface usage: class Foo { int x; char[] y; void read(Reader input) { input (x) (y); } void write(Writer output) { output (x) (y); } } Reader read; Writer write; auto foo = new Foo; write (foo); read (foo); Structs operate in a similar manner, but usage requires a bit more assistance to get the ball rolling (lack of interfaces): struct Foo { int x; char[] y; void read(Reader input) { input (x) (y); } void write(Writer output) { output (x) (y); } } Reader read; Writer write; auto foo = new Foo; write (&foo.write); read (&foo.read);
