transplant-code

To move code from one project to another without breaking functionality, you need to analyze source and target structures, adapt interfaces, reconcile dependencies, and port tests to ensure behavior remains intact.

Dependency reconciliation during project migration involves resolving build wiring and runtime assumptions between the source and target environments. This ensures the transplanted code integrates seamlessly without missing library conflicts.

Placement decisions for a transplanted module depend on analyzing compatibility and structure. You must evaluate whether to integrate the code into an existing package, create a new crate, or place it as a normal source file.

Code transplantation requires modifying the interface layer to ensure compatibility with the target project. This conservative adaptation approach minimizes API changes while preserving the original functionality.

To port tests when migrating a feature to a new repository, you must transfer the existing test suites and adapt them to the target project's runtime assumptions. This ensures the transplanted code behavior remains intact.

You should avoid conservative code transplantation when the source and target project structures have severe compatibility conflicts. If dependency reconciliation and minimal API changes cannot bridge the runtime assumptions, a rewrite is needed.
