NAME¶

std::function_ref::operator= - std::function_ref::operator=

Synopsis¶

constexpr function_ref& operator=( const function_ref& ) noexcept (1) (since C++26)
= default;
template< class T > (2) (since C++26)
constexpr function_ref& operator=( T ) = delete;

1) Copy assignment operator is explicitly-defaulted. std::function_ref satisfies
copyable and TriviallyCopyable. This defaulted assignment operator performs a
shallow copy of the stored thunk-ptr and bound-entity.
2) User-defined assignment operator is explicitly-deleted if T is not the same type
as std::function_ref, std::is_pointer_v<T> is false, and T is not a specialization
of std::nontype_t. This overload participates in overload resolution only if the
constraints are satisfied in the conditions above.

Return value¶

*this
