Function Bson.opt

Returns the native type for this BSON if it matches the current runtime type.


							
					T opt(T)
					(
					

					  T def = T.init
					

					);
					

					

					const(T) opt(T)
					(
					

					  const(T) def = (const(T)).init
					

					) const;

If the runtime type does not match the given native type, the 'def' parameter is returned instead.
