__GNU_PBDS::DETAIL::SYNTH_ACCESS_TRAITS(3cxx)

💅 NAME

okay so welcome to __gnu_pbds::detail::synth_access_traits< Type_Traits, Set, _ATraits > — it's the Synthetic element access traits, and yes bestie, this is one of those template-y little guys that does a lot of quiet heavy lifting. This page is from the 3cxx manual, part of libstdc++. 🫶

✨ SYNOPSIS

first things first, pull it in with:

#include <synth_access_traits.hpp>

and heads up: this struct inherits _ATraits — it's literally built on top of it, no cap. 🦋

🎀 Public Types

• base_type — typedef _ATraits base_type — the parent traits type, renamed so everything reads cute.
• const_iterator — typedef base_type::const_iterator const_iterator — the const iterator, straight borrowed from base_type.
• const_reference — typedef type_traits::const_reference const_reference — const reference type, courtesy of type_traits.
• key_const_reference — typedef type_traits::key_const_reference key_const_reference — const reference to a key, also from type_traits.
• type_traits — typedef Type_Traits type_traits — the Type_Traits template parameter, wearing a lowercase name. 💜

🌸 Public Member Functions

• synth_access_traits (const base_type &) — constructor that takes a const base_type &. that's it, that's the whole vibe.
• bool cmp_keys (key_const_reference, key_const_reference) const — compares two keys, returns bool. 🔥
• bool cmp_prefixes (const_iterator, const_iterator, const_iterator, const_iterator, bool compare_after=false) const — compares a pair of prefix ranges, with an optional bool compare_after that defaults to false. note that default, bestie, it's false here. 👀
• bool equal_keys (key_const_reference, key_const_reference) const — are the two keys equal? returns bool. simple, iconic.
• bool equal_prefixes (const_iterator, const_iterator, const_iterator, const_iterator, bool compare_after=true) const — checks whether prefixes are equal, with bool compare_after defaulting to true. ⚠️ highkey different default from cmp_prefixes — true here, false there. do not mix them up, i'm begging.

⭐ Static Public Member Functions

• static key_const_reference extract_key (const_reference) — static, so you don't need an instance to pull the key out of a reference. slay. ✨

🌈 Detailed Description

the actual declaration, in all its glory:

template<typename Type_Traits, bool Set, typename _ATraits>
    struct __gnu_pbds::detail::synth_access_traits< Type_Traits, Set, _ATraits >

Synthetic element access traits. that's the whole description. it's giving "synthetic", it's giving "element access traits", it's giving exactly what it says on the tin. 🎀

template parameters to keep straight: Type_Traits, bool Set, and _ATraits. three of them. don't lose one. 💀
