reference& operator=(basic_json other)

Replaces the contents with a copy of other. In case other is an rvalue, its value is moved.

• other: container to copy

*this

Linear in the size of other. If other is an rvalue, the operation has constant complexity.

The function's noexcept-specification is:

std::is_nothrow_move_constructible<value_t>::value and
std::is_nothrow_move_assignable<value_t>::value and
std::is_nothrow_move_constructible<json_value>::value and
std::is_nothrow_move_assignable<json_value>::value
