class JournalEntryView
Defined at line 24 of file ../../src/storage/lib/vfs/cpp/journal/entry_view.h
A view into the filesystem journal entry, including the header and footer.
This class does not have ownership over the underlying buffer, instead, it merely provides a
basic mechanism to parse a view of the buffer which is owned elsewhere.
