sizeHint method

int sizeHint(
  1. E value
)

If possible give a hint of expected size of the encoding.

This method is used inside default implementation of encode to avoid re-allocations.

Implementation

int sizeHint(E value) {
  final sizeTracker = SizeTracker();
  encodeTo(value, sizeTracker);
  return sizeTracker.size;
}
