Module plugin 

The LanguagePlugin trait + its PluginInput.

A plugin turns a workspace into nodes + edges at a requested level (analyze) and measures the per-file complexity metrics for its own language (metrics), returning the raw MetricInputs for the orchestrator to write. Measuring is a per-language concern — each plugin parses its own files with its own grammar and engine — so there is no central, by-extension metric dispatcher; but the writing (tier-2 derivation + node enrichment) and the language-agnostic derived data (cycles, Henry-Kafura, stats) are filled centrally by the orchestrator, so a plugin needs no dependency on the graph/enrichment crate. Plugins SELF-REGISTER via inventory::submit! into the registry; the CLI works only with that array through this trait and never names a concrete language.

Structs

PluginInput

Everything the orchestrator feeds a plugin from config + CLI input.

PluginRegistration

A self-registered language plugin. Each plugin in the plugins crate submits one via inventory::submit!; the binary’s registry is assembled by the linker, so NO central code lists the plugins and no caller (the CLI) ever names a language. Plugins are zero-sized unit structs, so a &'static reference is free.

Functions

Every self-registered language plugin. The CLI works only through this array and the LanguagePlugin trait — it never names a concrete language.
