Module engine 

Policy compilation and graph execution.

Turns a PolicyConfig (nodes + from/to edges from gateway.yaml) into a CompiledGraph with instantiated plugins, then walks that graph per request: success edges on Ok, error edges (or the policy-level catch-all handler) on failure, stopping at terminal client nodes.

Structs

BufferingReason

validate_policy tool both report to operators/agents.

CachePairWarning

Records that one node on an upstream’s success path forces buffering.

CompiledGraph

A compiled, ready-to-execute graph with instantiated plugins.

Functions

compile_policy

Compiles a PolicyConfig into a ready-to-execute CompiledGraph.

infer_stream_capability 🔒

For each upstream node, walks only the success/outcome ports forward to see whether anything before client reads the response body.

parse_edge_endpoint 🔒

Parses "node_id.port" into (node_id, port), defaulting the port to "out" when no dot is present. Splits on the last dot, so node IDs may themselves contain dots.

validate_cache_pairs 🔒

Checks that every proxy-cache pair agrees about where it caches.
