C++ concepts: MoveInsertable (since C++11)
From cppreference.com
Specifies that a rvalue of the type can be copied in uninitialized storage.
[edit] Requirements
The type T
is MoveInsertable
into the Container
X
if, given
A
|
the allocator type defined as X::allocator_type
|
m
|
the lvalue of type A obtained from X::get_allocator()
|
p
|
the pointer of type T* prepared by the container
|
rv
|
rvalue expression of type T , provided as the argument to push_back(), etc
|
the following expression is well-formed:
std::allocator_traits<A>::construct(m, p, rv);
The difference with CopyInsertable
is that the requirement is for an rvalue expression of type T
.
Note that if A
is std::allocator<T>, then this will call placement-new, as by ::new((void*)p) T(rv).
