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)
