NAME¶

std::any::operator= - std::any::operator=

Synopsis¶

any& operator=( const any& rhs ); (1) (since C++17)
any& operator=( any&& rhs ) noexcept; (2) (since C++17)
template< typename ValueType > (3) (since C++17)
any& operator=( ValueType&& rhs );

Assigns contents to the contained value.

1) Assigns by copying the state of rhs, as if by any(rhs).swap(*this).
2) Assigns by moving the state of rhs, as if by any(std::move(rhs)).swap(*this). rhs
is left in a valid but unspecified state after the assignment.
3) Assigns the type and value of rhs, as if by
any(std::forward<ValueType>(rhs)).swap(*this). This overload participates in
overload resolution only if std::decay_t<ValueType> is not the same type as any and
std::is_copy_constructible_v<std::decay_t<ValueType>> is true.

Template parameters¶

ValueType - contained value type

Type requirements¶

-
std::decay_t<ValueType> must meet the requirements of CopyConstructible.

Parameters¶

rhs - object whose contained value to assign

Return value¶

*this

Exceptions¶

1,3) Throws std::bad_alloc or any exception thrown by the constructor of the
contained type. If an exception is thrown, there are no effects (strong exception
guarantee).
