PipeGraphA Graph-based C++ Dataflow Pipeline Framework (DAG & Cyclic Graphs)

Zero-intrusion Node Definition · Graph as API · Batch & Stream Unified · Explicit Parallelism · Observable

🚀 Zero Intrusion

Use ordinary C++ classes/structs as nodes — no base class inheritance required

Work-stealing thread pool · Fixed-size memory pool · Move semantics zero-copy

Fluent API for building DAGs · Expressive · Type-safe

Lifecycle hooks · Execution tracing · Configurable error policies

Header-only design · No external runtime dependencies · Easily embed into any C++ project

Compile-time port type deduction · Automatic input/output type matching · Zero runtime type errors

Subgraph abstraction & nesting · Hierarchical pipeline construction · Reuse subgraphs as nodes
