Function `dmd.clone.buildOpAssign`

Build opAssign for struct. ref S opAssign(S s) { ... }


						
				extern(C++) FuncDeclaration buildOpAssign
				(
				

				  StructDeclaration sd,
				

				  dmd.dscope.Scope* sc
				

				);

Note that s will be constructed onto the stack, and probably copy-constructed in caller site.

If S has copy copy construction and/or destructor, the body will make bit-wise object swap: S _swap = this; // bit copy this = s; // bit copy _swap.dtor(); Instead of running the destructor on s, run it on tmp instead.

Otherwise, the body will make member-wise assignments: Then, the body is: this.field1 = s.field1; this.field2 = s.field2; ...;
