array::operator=

`array::operator=`

Assignment operators.

Synopsis

array&
operator=(
    array const& other); (1)

array&
operator=(
    array&& other); (2)

array&
operator=(
    std::initializer_list< value_ref > init); (3)

Description

Replaces the contents of the array.

(1) the contents are replaced with an element-wise copy of other.
(2) takes ownership of other's element storage if *storage() == *other.storage(); otherwise equivalent to (1).
(3) the contents are replaced with a copy of the values in init.

After (2), the moved-from array behaves as if newly constructed with its current storage pointer.

Complexity

(1) linear in size() + other.size().
(2) constant if *storage() == *other.storage(); otherwise linear in size() + other.size().
(1) linear in size() + init.size().

Exception Safety

(2) provides strong guarantee if *storage() != *other.storage() and no-throw guarantee otherwise. Other overloads provide strong guarantee. Calls to memory_resource::allocate may throw.

Return Value

*this
