organize-modules

You organize Rust modules by wrapping internal modules as private and using public re-exports in the root mod.rs. This presents a flat, stable API surface while preserving your crate's internal module hierarchy.

Use conditional visibility with cfg(any(test, doc)) to hide Rust crate internals in production builds. This keeps internals private while allowing documentation links and tests to reference the stable API surface.

Refactor large Rust crates by identifying candidate internal modules and wrapping them in private modules with public re-exports. This simplifies module paths and avoids API breakage during iterative changes.

Use private modules with public re-exports in Rust projects when dealing with module-heavy crates, library refactors, or domain modularization. It helps maintain a clean, stable API surface while preserving internal structure.

No, using cfg(any(test, doc)) for conditional visibility does not affect production builds in Rust. It ensures internal details remain hidden in production builds while only exposing them for documentation and test environments.

To apply the pattern in a Rust mod.rs file, identify internal modules, wrap them privately, add public re-exports to flatten the API, and apply conditional visibility for docs and tests. Verify correctness using cargo test and cargo doc.
