mongo::dur::WriteIntent Struct Reference

Declaration of an intent to write to a region of a memory mapped view. More...

#include <dur_commitjob.h>

Detailed Description

Declaration of an intent to write to a region of a memory mapped view.

We store the end rather than the start pointer to make operator < faster since that is heavily used in set lookup.
