Member Data Documentation

boundary

size_type pw::multibuf_impl::Entry::View::boundary

Flag that is set when adding an entry or consolidating several entries in a new layer. It is used to determine how many entries represent a packet or message fragment at a particular protocol layer.

sealed

size_type pw::multibuf_impl::Entry::View::sealed

Flag that is set when a layer should not be modified or removed. This can be used by lower levels of a protocol stack to indicate that upper or application layers should not modify data. This is informational and bypassable, and so should not be considered a security mechanism.
