Move assignment.

Synopsis
value&
operator=(
    value&& other);
Description

The contents of the value are replaced with the contents of other using move semantics:

  • If *other.storage() == *sp, ownership of the underlying memory is transferred in constant time, with no possibility of exceptions. After assignment, the moved-from value becomes a null with its current storage pointer.
  • If *other.storage() != *sp, an element-wise copy is performed if other.is_structured() == true, which may throw. In this case, the moved-from value is not changed.
Complexity

Constant, or linear in this->size() plus other.size().

Exception Safety

Strong guarantee. Calls to memory_resource::allocate may throw.

Parameters

Name

Description

other

The value to assign from.
