Detailed Description

A database snapshot.

This is a fake wrapper class for sqlite3_snapshot.

Use database::get_snapshot to create snapshot objects.

Since

SQLite 3.10

Requires THINSQLITEPP_ENABLE_EXPIREMENTAL macro to be defined to 1 as the underlying SQLite feature is experimental.

#include <thinsqlitepp/snapshot.hpp>
