Crate rill_graph 

Rill Graph — Static DAG Signal Graph

This crate provides an immutable signal graph with static topology. Build once with GraphBuilder. The graph is a pure topology description — build_ir() produces a rill_lang::graph_ir::GraphIr, which rill-lang’s rill_lang::graph_compiler::compile transforms into a rill_lang::graph_engine::CompiledGraphEngine for execution.

Key Features

• Static DAG topology — connections are fixed after build
• Kahn’s algorithm — automatic topological sort with cycle detection
• Auto FanOut/FanIn — connections classified by topology (user never chooses)
• GraphIr — intermediate representation for rill-lang compilation
