Module plugins 

Two-tier plugin system: native Rust plugins (native) and scripted plugins (script). Defines the Plugin trait — the contract every graph node implements — and create_plugin, the single factory that maps node-type strings from YAML config to plugin instances.

Modules

native

Native (built-in) plugins implemented in Rust. Each submodule provides one node type; instances are constructed by crate::plugins::create_plugin.

ports

Static port declarations for every node type.

resources

Process-wide services shared by every plugin instance.

script

Scripted plugin host (script).

util

Shared utilities for plugins.

Structs

PluginExecutionError

An error that occurs during plugin execution. The context is preserved so the graph engine can route it through the error port.

PluginOutput

The result of a successful plugin execution.

Constants

KNOWN_PLUGIN_TYPES

Every plugin type create_plugin can build, for save-time validation of references to plugin types (e.g. a shared config’s type). Guarded against drift from the factory’s match arms by test_known_plugin_types_matches_factory.

Traits

Plugin

Every plugin (native or scripted) implements this trait.

Functions

create_plugin

Creates a plugin instance from a node type string and its YAML-derived config.

port_spec

Static port declaration for a node type. None for unknown types.

Type Aliases

PluginResult

The result of a plugin execution: either success or an error with the context preserved.
