What problem does it solve?

Downgrading Rust editions from 2024 to 2021 can fail due to let-chain usage in if-let expressions. This guide provides a structured approach to identifying, refactoring, and validating code so that codebases compile under Rust 2021 without losing behavior.

Core Features & Use Cases

  • Detects and catalogs let-chain occurrences across files.
  • Offers concrete refactoring patterns to replace let chains with 2021-compatible forms.
  • Includes guidance for updating test code and Cargo.toml edition to ensure successful migration.

Quick Start

Use the downgrade workflow to convert a Rust project from edition 2024 to 2021 by replacing let-chain patterns with nested if-let blocks and updating Cargo.toml accordingly.
