R.36: Have a const shared_ptr& parameter to specific that it would keep a reference rely to the object ???

No. The GSL exists only to supply several forms and aliases that are not at this time while in the common library. In case the committee decides on standardized versions (of these or other varieties that fill precisely the same need to have) then they can be removed from the GSL.

To simplify code and eradicate a necessity for specific memory administration. To provide an object right into a surrounding scope, thereby extending its life time.

Flag a parameter of a smart pointer style (a type that overloads operator-> or operator*) that is definitely copyable/movable but never copied/moved from inside the perform body, and that is under no circumstances modified, and that isn't passed along to another perform which could do so.

Some rules purpose to enhance different varieties of safety while others intention to reduce the likelihood of mishaps, several do both.

are retained for for much longer than essential and that unanticipated usage of is and fn could come about afterwards while in the function.

To find function objects and features described in a individual namespace to “customize” a standard perform.
