◆ operator()() [1/2]

template<typename I , typename S , typename V , typename P = ident, requires = (InputIterator<I>() && Sentinel<S, I>() && IndirectRelation<equal_to, projected<I, P>, V const *>())>
I ranges::v3::find_fn::operator() ( begin,
end,
V const &  val,
proj = P{} 
) const

template function find_fn::operator()

range-based version of the find std algorithm

Precondition
Rng is a model of the Range concept
I is a model of the InputIterator concept
S is a model of the Sentinel<I> concept
P is a model of the Invocable<iter_common_reference_t<I>> concept
The ResultType of P is EqualityComparable with V

◆ operator()() [2/2]

template<typename Rng , typename V , typename P = ident, typename I = iterator_t<Rng>, requires = (InputRange<Rng>() && IndirectRelation<equal_to, projected<I, P>, V const *>())>
safe_iterator_t<Rng> ranges::v3::find_fn::operator() ( Rng &&  rng,
V const &  val,
proj = P{} 
) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
