Detailed Description

This class represents a parsed redo record.

Note

The body field refers to the original parsing buffer, so a caller must ensure that the buffer's lifetime is not less than the parsed record's lifetime.

Member Enumeration Documentation

Kind

enum class ib::redo::Record_view::Kind
