-# The handling of sizes is somewhat complex, as there are several types of size:
-# * nw_size
-# This is the network size, i.e. the number of bytes on the network
-#
-# * mem_size
-# The total amount of memory used for the representation of something inside
-# spice. This is generally sizeof(C struct), but can be larger if for instance
-# the type has a variable size array at the end or has a pointer in it that
-# points to another data chunk (which will be allocated after the main
-# data chunk). This is essentially how much memory you need to allocate to
-# contain the data type.
-#
-# * extra_size
-# This is the size of anything that is not part of the containing structure.
-# For instance, a primitive (say uint32_t) member has no extra size, because
-# when allocating its part of the sizeof(MessageStructType) struct. However
-# a variable array can be places at the end of a structure (@end) and its
-# size is then extra_size. Note that this extra_size is included in the
-# mem_size of the enclosing struct, and even if you request the mem_size
-# of the array itself. However, extra_size is typically not requested
-# when the full mem_size is also requested.
-#
-# extra sizes come in two flavours. contains_extra_size means that the item
-# has a normal presence in the parent container, but has some additional
-# extra_size it references. For instance via a pointer somewhere in it.
-# There is also is_extra_size(). This indicates that the whole elements
-# "normal" mem size should be considered extra size for the container, so
-# when computing the parent mem_size you should add the mem_size of this
-# part as extra_size
