C++ concepts: TriviallyCopyable

From cppreference.com
< cpp‎ | concept
 
 
 

[edit] Requirements

  • Trivial or deleted (since C++14) copy constructor
  • Trivial or deleted (since C++14) move constructor
  • Trivial or deleted (since C++14) copy assignment operator
  • Trivial or deleted (since C++14) move assignment operator
  • at least one copy constructor, move constructor, copy assignment operator, or move assignment operator is non-deleted
(since C++14)

Scalar types and arrays of TriviallyCopyable objects are TriviallyCopyable as well, as well as the const-qualified (but not volatile-qualified) versions of such types.

[edit] Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
CWG 1734 C++14 C++03 POD with deleted non-trivial assignment was not trivial deleted ctors/operators allowed
