hyper-0-14-to-1-0

Automate deterministic parts of the Rust hyper migration from v0.14 to v1.x for legacy client usage.

What it does

Rust source updates

• Rewrites legacy client imports:
  • use hyper::Client; -> use hyper_util::client::legacy::Client;
  • use hyper::client::HttpConnector; -> use hyper_util::client::legacy::connect::HttpConnector;
  • use hyper::client::connect::HttpConnector; -> use hyper_util::client::legacy::connect::HttpConnector;
• Rewrites grouped imports:
  • use hyper::{Body, Client}; -> split into use hyper::{Body}; and use hyper_util::client::legacy::Client;
• Rewrites fully-qualified type paths in code:
  • hyper::Client -> hyper_util::client::legacy::Client
  • hyper::client::HttpConnector -> hyper_util::client::legacy::connect::HttpConnector

Usage

bash
Copy
# Validate the workflow
bunx codemod@latest workflow validate -w workflow.yaml

# Dry run against your project
bunx codemod@latest workflow run -w workflow.yaml --target /path/to/your/rust/project

# Run the package from the registry
bunx codemod@latest hyper-0-14-to-1-0 --target /path/to/your/rust/project

Manual follow-up

After running, you should:

1. Update Cargo.toml to Hyper 1 and add hyper-util with required features for your runtime/protocol usage
2. Review client construction sites and switch to the Hyper v1 builder APIs where needed
3. Migrate body handling (to_bytes, body types, and response collection) as needed for your codebase
4. Run cargo check and cargo test

Development

bash
Copy
# Run tests
bunx codemod@latest jssg test -l rust ./scripts/codemod.ts -v --strictness loose

# Validate workflow
bunx codemod@latest workflow validate -w workflow.yaml
