constexpr const Pred& pred() const;		(since C++20)

Returns a reference to the stored predicate.

If *this does not store a predicate (e.g. an exception is thrown on the assignment to *this, which copy-constructs or move-constructs a Pred), the behavior is undefined.

Parameters

(none)

Return value

a reference to the stored predicate
