Functions
std::int64_t	wowlib::db::detail::readInt (std::span< const std::byte > image, std::size_t &pos, std::size_t bytes, bool isSigned)
	Read a little-endian integer of bytes bytes at pos, sign-extended when isSigned, advancing pos.
void	wowlib::db::detail::writeInt (FileBuffer &out, std::int64_t value, std::size_t bytes)
	Append value's low bytes bytes (little-endian) to out.
void	wowlib::db::detail::decodeInlineRecord (std::span< const Column > schema, std::size_t record, std::span< const std::byte > image, RecordSink &sink, TableState &state)
	Decode one fixed-stride record's inline fields into sink and journal its string offsets (record then schema then element order).
void	wowlib::db::detail::encodeInlineRecord (std::span< const Column > schema, const RecordSource &source, std::size_t record, FileBuffer &out, StringPool &pool, const TableState &state, std::size_t &cursor)
	Encode one fixed-stride record's inline fields from source, appending to out and resolving strings through pool (cursor tracks the journal).
