__GNU_PBDS::QUADRATIC_PROBE_FN(3)
π __gnu_pbds::quadratic_probe_fn< Size_Type > π
okay bestie, welcome to the libstdc++ manual β this one lives in the Library Functions Manual section, and yes it's the __gnu_pbds::quadratic_probe_fn< Size_Type > page. buckle up, it's short but it's β¨importantβ¨.
πΈ NAME πΈ
__gnu_pbds::quadratic_probe_fn< Size_Type > β a probe sequence policy that uses square increments. that's it, that's the whole vibe. it tells a hash table where to look next when the first spot is taken. no cap.
π¦ SYNOPSIS π¦
#include <hash_policy.hpp>
β Public Types
typedef Size_Type size_type
π Public Member Functions
void swap (quadratic_probe_fn< Size_Type > &other)
π Protected Member Functions
size_type operator() (size_type i) const- returns the i-th offset from the hash value. lowkey the whole point of the class.
π Detailed Description π
template<typename Size_Type = std::size_t>
class __gnu_pbds::quadratic_probe_fn< Size_Type >
"A probe sequence policy using square increments." π
that's the official tagline and honestly? iconic. it's giving "I make hashing go brrr by jumping in squares." if you're plugging this into a hash policy, this is the one that does the quadratic thing. periodt.

template<typename Size_Type> quadratic_probe_fn< Size_Type >::size_type __gnu_pbds::quadratic_probe_fn< Size_Type >::operator() (size_type i) const [inline], [protected]
bestie, this is the one you actually care about. it returns the i-th offset from the hash value. π«
note the<purple>[inline]</purple>and<purple>[protected]</purple>tags β it's inline and it's protected, so it's doing its little job behind the scenes, not out here in the public API. iykyk.
