From 61e5bcef2629e2d68b805a956a96fff264d4f74d Mon Sep 17 00:00:00 2001 From: untodesu Date: Sat, 28 Jun 2025 01:59:49 +0500 Subject: Restructure dependencies and update to C++20 - Nuked static_assert from almost everywhere in the project - Nuked binary dependency support. Might add one later though - Separated dependency headers into a separate include subdirectory - Grafted a thirdpartylegalnotices.txt generator from RITEG - Pushed development snapshot version to 2126 (26th week of 2025) --- deps/include/entt/resource/cache.hpp | 413 ----------------------------------- 1 file changed, 413 deletions(-) delete mode 100644 deps/include/entt/resource/cache.hpp (limited to 'deps/include/entt/resource/cache.hpp') diff --git a/deps/include/entt/resource/cache.hpp b/deps/include/entt/resource/cache.hpp deleted file mode 100644 index e17260b..0000000 --- a/deps/include/entt/resource/cache.hpp +++ /dev/null @@ -1,413 +0,0 @@ -#ifndef ENTT_RESOURCE_RESOURCE_CACHE_HPP -#define ENTT_RESOURCE_RESOURCE_CACHE_HPP - -#include -#include -#include -#include -#include -#include -#include -#include "../container/dense_map.hpp" -#include "../core/compressed_pair.hpp" -#include "../core/fwd.hpp" -#include "../core/iterator.hpp" -#include "../core/utility.hpp" -#include "fwd.hpp" -#include "loader.hpp" -#include "resource.hpp" - -namespace entt { - -/*!
