Built with a "Dual-Engine" architecture targeting AVX2 and AVX-512, it pushes x86 hardware to its absolute physical limits. +Tachyon 0.7.6 represents the pinnacle of AVX2 optimization. By implementing a **Single-Pass Structural & UTF-8 Kernel** and **Small Buffer Optimization (SBO)**, Tachyon outperforms Simdjson OnDemand in specific latency-critical scenarios while maintaining full data safety. -### πŸ† Benchmark Results: AVX-512 ("God Mode") -*Environment: [ISA: AVX-512 | ITERS: 50 | WARMUP: 20]* +### πŸ† Benchmark Results (AVX2) +*Environment: [ISA: AVX2 | ITERS: 2000 | MEDIAN CALCULATION]* -At the throughput levels shown below, the margin of error is so minuscule that **Tachyon** and **Simdjson** are effectively tied for the world record. Depending on the CPU's thermal state and background noise, either library may win by a fraction of a percent. +Tachyon **Turbo Mode** excels at **Low-Latency Key Access**, finding keys in large files orders of magnitude faster than streaming parsers by skipping parsing entirely.

Mode::Turbo (The Throughput King) -Optimized for Big Data analysis where every nanosecond counts. -* **Technology**: **Vectorized Depth Skipping**. Tachyon identifies object boundaries using SIMD and "teleports" over nested content to find array elements at memory-bus speeds. +## πŸ›οΈ Modes of Operation -### 2. Mode::Apex (The Typed Speedster) -The fastest way to fill C++ structures from JSON. -* **Technology**: **Direct-Key-Jump**. Instead of building a DOM, Apex uses vectorized key searches to find fields and maps them directly to structs using zero-materialization logic. +### 1. Mode::Turbo (Lazy / On-Demand) +The default mode for maximum throughput. +* **Technology**: **Single-Pass AVX2 Kernel**. Computes structural indices and validates UTF-8 in a single pass over memory. +* **Lazy Indexing**: Can skip entire sub-trees of JSON without parsing them, enabling O(1) effective latency for lookups in large files. +* **Safety**: **Full UTF-8 Validation** is enabled by default. -### 3. Mode::Standard (The Balanced Warrior) -Classic DOM-based access with maximum flexibility. -* **Features**: Full **JSONC** support (single-line and block comments) and materialized access to all fields. +### 2. Mode::Apex (Typed / Struct Mapping) +The fastest way to fill C++ structures from JSON or CSV. +* **Technology**: **Direct-Key-Jump**. Maps JSON fields directly to your C++ structs (`int`, `string`, `vector`, `bool`, etc.). -### 4. Mode::Titan (The Tank) -Enterprise-grade safety for untrusted data. -* **Hardening**: Includes **AVX-512 UTF-8 validation** kernels and strict bounds checking to prevent crashes or exploits on malformed input. +### 3. Mode::CSV (New!) +High-performance CSV parsing support. +* **Features**: Parse CSV files into raw rows or map them directly to C++ structs using the same reflection system as JSON. Handles escaped quotes and multiline fields correctly. --- ## πŸ› οΈ Usage Guide -### Turbo Mode: Fast Analysis -Best for counting elements or calculating statistics on huge buffers. - +### Turbo Mode: Lazy Analysis ```cpp #include "Tachyon.hpp" Tachyon::Context ctx; -auto doc = ctx.parse_view(buffer, size); // Zero-copy view +// Zero-copy view, validates UTF-8, parses structure on demand +auto doc = ctx.parse_view(buffer, size); if (doc.is_array()) { - // Uses the "Safe Depth Skip" AVX path for record-breaking speed + // Uses optimized AVX2 skipping to count elements instantly size_t count = doc.size(); } ``` -### Apex Mode: Direct Struct Mapping -Skip the DOM entirely and extract data into your own types. - +### Apex Mode: Typed JSON ```cpp struct User { - int64_t id; + uint64_t id; std::string name; + std::vector scores; }; -// Non-intrusive metadata -TACHYON_DEFINE_TYPE_NON_INTRUSIVE(User, id, name) +// Define reflection +TACHYON_DEFINE_TYPE_NON_INTRUSIVE(User, id, name, scores) int main() { - Tachyon::json j = Tachyon::json::parse(json_string); User u; - j.get_to(u); // Apex Direct-Key-Jump fills the struct instantly + Tachyon::json::parse(json_string).get_to(u); } ``` ---- +### CSV Mode +```cpp +// Raw Rows +auto rows = Tachyon::json::parse_csv(csv_string); -## 🧠 Architecture: The Dual-Engine -Tachyon detects your hardware at runtime and hot-swaps the parsing kernel. -* **AVX2 Engine**: 32-byte-per-cycle classification using `vpshufb` tables. -* **AVX-512 Engine**: 64-byte-per-cycle classification leveraging `k-mask` registers for branchless filtering. +// Typed Objects +auto users = Tachyon::json::parse_csv_typed(csv_string); +``` --- -## πŸ›‘οΈ Licensing & Support Policy +## πŸ’° Licensing & Support -**Business Source License 1.1 (BSL)** +**Tachyon v7.x is a PAID COMMERCIAL PRODUCT.** -Tachyon is licensed under the BSL.
