Job::usessilently discards run-job configuration.
Job::useskeeps onlyself.valueand replaces the config with a freshUsesJob. A caller that sets run-specific fields first, for exampleJob::new("x").add_step(...).uses(...), loses those steps without any error. Consider movingusesto a constructor that does not accept a configured run job, for exampleJob::uses(owner, repo, path, version)plus a separatenamesetter, so the type system prevents the loss.🤖 Prompt for AI Agents

Duplicate flattened field names can break Job serialization and deserialization.
Job<J> flattens both config and value. RunJob and JobValue declare the same field names (runs_on, environment, outputs, env, defaults, timeout_minutes, continue_on_error, container, services, steps, retry, artifacts), and UsesJob and JobValue share uses, with, and secrets. If both sides hold Some, serialization emits duplicate mapping keys. On deserialization, the same input key can feed both flattened structs, so a round trip does not restore the original split.
Job is public and derives Serialize/Deserialize, so external users can hit this. Consider marking the duplicated JobValue fields as #[serde(skip)]-equivalent on the Job path, or dropping Serialize/Deserialize from Job and keeping serialization on JobValue only, since Jobs stores JobValue.
Run the following script to check whether Job is serialized or deserialized anywhere:
#!/bin/bash

Similar to how steps are handled, this PR introduces the same abstraction for jobs - since jobs invoking reusable workflows are vastly different from "normal" jobs, they share barely any configuration. However, with what is currently available, one could easily define a job that contained invalid combinations when working with reusable workflows (or for that matter, even with the more common type of workflows).
With the changes here, this adds a strict differentiation between the different kind of jobs by utilizing the type system, making invalid jobs unrepresentable.
We've been using this upstream in the Zed repo for quite some time now without any issues. I also contributed to
derive_settersto make this properly possible in the first place (thus the bump in this PR). At the same time, I acknowledge this is a bigger change than the previous ones, happy to discuss this as needed.Notably, a breaking change this introduces is that getting a job now returns a
JobValueas opposed to aJobdue to the change to the types.Summary by CodeRabbit
