[Rust] Update reqwest to 0.13 and reqwest-middleware to 0.5 by adi-code · Pull Request #22816 · OpenAPITools/openapi-generator

adi-code · 2026-01-26T15:13:41Z

This PR updates reqwest (v0.13) and reqwest-middleware (v0.5) dependencies (closes #22621). It aims to replace PR #22630 - I tried to contribute to that PR, but I didn't hear back from the author. I hope this approach is fine, I'm dedicated to actively updating this PR until it's merged.

Changes introduced with reqwest 0.13 are described here: https://seanmonstar.com/blog/reqwest-v013-rustls-default/

query() and form() methods require "query" and "form" features
BREAKING: Upgraded reqwest-middleware from ^0.4 to ^0.5 for reqwest 0.13 compatibility
BREAKING: Renamed feature rustls-tls to rustls to match reqwest 0.13's renamed feature

PR checklist

Read the contribution guidelines.
Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
Run the following to build the project and update samples:
```
./mvnw clean package || exit
./bin/generate-samples.sh ./bin/configs/*.yaml || exit
./bin/utils/export_docs_generators.sh || exit
```
(For Windows users, please run the script in WSL)
Commit all changed files.
This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
These must match the expectations made by your contribution.
You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Summary by cubic

Upgrade Rust client generator to reqwest 0.13 and reqwest-middleware 0.5, enabling query and form features and aligning TLS feature names. This keeps generated clients current and resolves type conflicts with middleware. Fixes #22621.

Dependencies
- Bump reqwest to ^0.13 and reqwest-middleware to ^0.5 across templates and samples.
- Enable "query" and "form" features for all client variants and middleware.
- Rename feature "rustls-tls" to "rustls" to match reqwest 0.13.

^{Written for commit 18a5307. Summary will update on new commits.}

@wing328 I filed the PR against master, but please let me know if you think 8.0.x will be more relevant. I can also add fallbacks for reqwest 0.12.x.

I can also add fallbacks for reqwest 0.12.x.

for dependency update, we usually go with the upcoming minor releases, which is v7.20.0

wing328 · 2026-01-26T16:16:46Z

can you please merge the latest master into your branch and regenerate the samples again?

Update the Rust client generator template to use reqwest 0.13 instead of 0.12, as requested in issue OpenAPITools#22621. In reqwest 0.13, the `query()` and `form()` methods have been moved behind feature flags and are disabled by default. Since the generated Rust clients extensively use both methods, these features must be explicitly enabled. Changes: - Updated all reqwest dependencies from ^0.12 to ^0.13 - Added "query" and "form" to reqwest feature flags for all variants: - Blocking client configuration - Async client with file stream support - Async client without file stream - Reqwest-trait variant - Updated reqwest-middleware features for consistency This maintains full backward compatibility as only the dependency version and features change. The API surface of generated code remains identical. Fixes OpenAPITools#22621

In reqwest 0.13, the rustls-tls feature was renamed to rustls. This updates the Cargo.mustache template and all generated samples to use the new feature name, fixing CI build failures when using --all-features flag.

The previous reqwest-middleware 0.4 depends on reqwest 0.12, which caused type conflicts when upgrading to reqwest 0.13: - reqwest::Error (from reqwest 0.13) - reqwest_middleware::reqwest::Error (from reqwest 0.12 via middleware) These are different types from different versions of reqwest. reqwest-middleware 0.5 is compatible with reqwest 0.13, resolving the version conflict. With both using the same reqwest version, the re-exported types are now correctly aligned.

It adds "query" and "form" features for reqwest-middleware crate in petstore-async-middleware example and Cargo.mustache template.
