Flatbuffer serialization for scalar fields

[Gaurav Jain]

Does absent fields also occupies space in serialise Flatbuffer object ? If not, then how does mutation for scalar entries work ? I can understand the mutation of non-scalar entries where we need to relocate older Flatbuffer content to new memory location.

No, absent fields do not occupy space. That indeed means that by default, mutation functions fail (notice they return a bool), if you try to set a field that is not present.

If you intend to use a buffer with mutation, it may be worth to construct it using `force_defaults` such that all scalars are present.
