VarStreamArrayExtractor is intended to be specialized to provide customized extraction logic...
static Error initialize(BinaryStreamRef Stream, DbiModuleDescriptor &Info)
The header preceeding each entry in the Module Info substream of the DBI stream.
Definition: RawTypes.h:223
static ErrorSuccess success()
Create a success value.

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.
Error operator()(BinaryStreamRef Stream, uint32_t &Length, pdb::DbiModuleDescriptor &Info)
Lightweight error class with error context and mandatory checking.
