Replace all manual component references

[ERnsTL]

Task 6 — Integrate Generated Code into main.rs

Objective

Replace all manual component references.

Requirements

1. Add:

include!(concat!(env!("OUT_DIR"), "/build_generated.rs"));

2. Replace:

• Manual use imports
• Manual metadata registration
• Manual factory match
• Manual logging filters

With:

register_component_log_filters(&mut logger);

let componentlib = build_component_library();

if let Some(component) = instantiate_component(name, args) {
    component.run();
}

Acceptance Criteria

• main.rs contains no component-specific references.

• Adding a new component requires:

  • Cargo dependency
  • flowd.build.toml entry

• No source edits required.

Task 6 status update

Task 6 is mostly implemented, but not fully complete against its acceptance criteria.

Completed

• main.rs now includes generated build output via:
  • include!(concat!(env!("OUT_DIR"), "/build_generated.rs"));
• Manual component wiring for:
  • imports,
  • metadata registration,
  • factory matching,
  • log filter registration
    has been replaced by generated code from build.rs.
• Component lifecycle was split to match the required pattern:
  • instantiate_component(...) returns an instantiated component,
  • run() is called by the caller.

Still undone

• Acceptance criterion not yet met: main.rs still contains component-specific references (e.g. hardcoded bootstrap/test graph nodes like Repeat, Drop, Output).
• Because of that, the criterion “main.rs contains no component-specific references” is still open.
• Consequently, “no source edits required” is not fully guaranteed for all component-related behavior beyond generated registration/factory paths.

Proposed follow-up

• Remove/parameterize remaining hardcoded component names in main.rs bootstrap/default graph/test setup so component selection is fully config-driven (flowd.build.toml + Cargo dependency only).
