/*
* Symbols for 'template metaprogramming' (compile-time template programming),
* inspired by the MPL of Aleksey Gurtovoy and David Abrahams, and the Mp11 of Peter Dimov and Bjorn Reese.
*
* Currently, the focus is on facilitating advanced type filtering,
* such as filtering columns by constraints having various traits.
* Hence it contains only a very small subset of a full MPL.
*
* Three key concepts are critical to understanding:
* 1. A 'trait' is a class template with a nested `type` typename.
* The term 'trait' might be too narrow or not entirely accurate, however in the STL those class templates are summarized as "Type transformations".
* hence being "transformation type traits".
* It was the traditional way of transforming types before the arrival of alias templates.
* E.g. `template<class T> struct x { using type = T; };`
* They are of course still available today, but are rather used as building blocks.
* 2. A 'metafunction' is an alias template for a class template or a nested template expression, whose instantiation yields a type.
* E.g. `template<class T> using alias_op_t = typename x<T>::type`
* 3. A 'quoted metafunction' (aka 'metafunction class') is a certain form of metafunction representation that enables higher-order metaprogramming.
* More precisely, it's a class with a nested metafunction called "fn".
* Correspondingly, a quoted metafunction invocation is defined as invocation of its nested "fn" metafunction.
*
* Conventions:
* - "Fn" is the name of a template template parameter for a metafunction.
* - "Q" is the name of class template parameter for a quoted metafunction.
* - "_fn" is a suffix for a class or alias template that accepts metafunctions and turns them into quoted metafunctions.
* - "higher order" denotes a metafunction that operates on another metafunction (i.e. takes it as an argument).

/**
* This is a cute function used to replace migration up/down functionality.
* It performs check storage schema with actual db schema and:
* * if there are excess tables exist in db they are ignored (not dropped)
* * every table from storage is compared with it's db analog and
* * if table doesn't exist it is being created
* * if table exists its colums are being compared with table_info from db and
* * if there are columns in db that do not exist in storage (excess) table will be dropped and
* recreated
* * if there are columns in storage that do not exist in db they will be added using `ALTER TABLE
* ... ADD COLUMN ...' command
* * if there is any column existing in both db and storage but differs by any of
* properties/constraints (pk, notnull, dflt_value) table will be dropped and recreated. Be aware that
* `sync_schema` doesn't guarantee that data will not be dropped. It guarantees only that it will make db
* schema the same as you specified in `make_storage` function call. A good point is that if you have no db
* file at all it will be created and all tables also will be created with exact tables and columns you
* specified in `make_storage`, `make_table` and `make_column` calls. The best practice is to call this
* function right after storage creation.
* @param preserve affects function's behaviour in case it is needed to remove a column. If it is `false`
* so table will be dropped if there is column to remove if SQLite version is < 3.35.0 and remove column if SQLite version >= 3.35.0,
* if `true` - table is being copied into another table, dropped and copied table is renamed with source table name.
* Warning: sync_schema doesn't check foreign keys cause it is unable to do so in sqlite3. If you know how to get foreign key info please
* submit an issue https://github.com/fnc12/sqlite_orm/issues
* @return std::map with std::string key equal table name and `sync_schema_result` as value.
* `sync_schema_result` is a enum value that stores table state after syncing a schema. `sync_schema_result`
* can be printed out on std::ostream with `operator<<`.
