C++ concepts: MoveConstructible (since C++11)
Specifies that an instance of the type can be move-constructed (moved). This means that type has move semantics: that is, can transfer its internal state to a new instance of the same type potentially minimizing the overhead.
The type must meet
CopyConstructible requirements and/or implement the following functions:
Type::Type( Type&& other );
Type::Type( const Type&& other );
|(One of the variants is sufficient)|
Move constructor: constructs an instance of a type with the contents of
other. The internal state of
other is unspecified after the move. However, it must still be valid, that is, no invariants of the type are broken.
The following expressions must have the specified effects:
|Type a = rv;|| |
|Type(rv);|| a temporary object of type |
| checks if a type has a move constructor |
