/*
|
|
* Symbols for 'template metaprogramming' (compile-time template programming),
|
|
* inspired by the MPL of Aleksey Gurtovoy and David Abrahams.
|
|
*
|
|
* 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.
|
|
*
|
|
* Two key concepts are critical to understanding:
|
|
* 1. A 'metafunction' is a class template that represents a function invocable at compile-time.
|
|
* 2. A '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 metafunction class invocation is defined as invocation of its nested "fn" metafunction.
|
|
* 3. A 'metafunction operation' is an alias template that represents a function whose instantiation already yields a type.
|
|
*
|
|
* Conventions:
|
|
* - "Fn" is the name for a metafunction template template parameter.
|
|
* - "FnCls" is the name for a metafunction class template parameter.
|
|
* - "_fn" is a suffix for a type that accepts metafunctions and turns them into metafunction classes.
|
|
* - "higher order" denotes a metafunction that operates on another metafunction (i.e. takes it as an argument).

* Difference with the previous function is that previous override has `double` as return type but this

* override accepts return type from you as a template argument. You can use any bindable type:
|
|
* `float`, `int`, `std::optional<double>` etc. This override is handy when you expect `null` as result.
|
|
*
|
|
* Example:
|
|
*
|
|
* auto rows = storage.select(sqlite_orm::trunc<float>(5.5)); // decltype(rows) is std::vector<float>

* * every table from storage is compared with it's db analog and

* * if there are columns in storage that do not exist in db they will be added using `ALTER TABLE

* * if there is any column existing in both db and storage but differs by any of
|

* `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
