ProcessSnapshotMinidump. ModuleSnapshotMinidump is currently only capable of reading module annotations, in both vector and simple-dictionary forms. It does not read any other module information from minidump files. These annotations are all that are necessary to be able to upload Crashpad-produced minidumps to Breakpad crash processor servers, because Breakpad accepts them as HTTP POST parameters, while Crashpad places them in the minidump file itself.
