Available Headers

Collections (fond/collections/)

Policy-based data structures with compile-time Ordered/Frozen variants:

• Set — unordered, ordered, frozen, frozen-ordered (policy-based)
• Map — same four variants via policies
• List / Tuple — mutable list + frozen tuple
• BloomFilter / BloomSet — probabilistic fast-negative-lookup set
• LRUCache — simpoo version wrapping Map
• RingBuffer — fixed-size circular buffer, compile-time sized
• Trie — prefix tree for string lookup and autocomplete
• BitFlag — type-safe enum-keyed bitset wrapper
• Arena — bump allocator for bulk allocation
• Pool — fixed-size typed object pool with freelist
• SparseSet — O(1) add/remove/contains with dense iteration
• DynStack — dynamic LIFO stack, doubles as a freelist

Collections Core (fond/collections/core/)

Composable low-level building blocks for high-performance data structures:

• OpenMap — open-addressing hash map with tombstones, node pool, intrusive LRU list
• IntrusiveList — doubly-linked list that doesn't own nodes
• NodePool — pre-allocated typed pool for ListNode-derived types
• HashUtils — probing, power-of-2 masking, hash mixing, load factor math

High-Performance (fond/collections/)

• FastLRU — LRU cache built on OpenMap (zero allocations per get/put)

Colors (fond/colors/)

• Color — RGBA color struct with conversions to ANSI, ImGui, uint32
• Palette — named color constants (single source of truth)
• ANSI — terminal color constants (constexpr, zero allocation)
• ImGui — ImVec4/ImU32 color constants (generated from palette)

Logger (fond/logger/)

• Compile-time configurable logging with function pointer dispatch
• ANSI color support, file output with rotation, buffer mode, callbacks
• std::format template overloads on all log methods

Info (fond/info/)

• ProjectInfo — version, exit codes, project metadata with pybind11 bindings
• VersionHelpers — version bump/parse utilities

MsgPack (fond/msgpack/)

• Binary serialization with MSGPACK_DEFINE macro (powered by FOND_FOR_EACH)
• Packer, Unpacker, Python packer/unpacker variants

Lua (fond/lua/)

• Lua table serialization with LUA_DEFINE macro (powered by FOND_FOR_EACH)

Macros (fond/macros/)

• FOND_FOR_EACH — preprocessor for-each over variadic args (generated, up to 100 args)

Tools

• ByteBuffer — unified read/write byte buffer
• Timer — scoped timer with auto unit selection, lap times, time_it() lambda
• EpochTimestamp — configurable timestamp formatting
• KeyStore — file-backed key/value store using MsgPack
• Locking — mutex helpers (C and C++ variants)
