This PR adds the all_token_ids to the Request class, which is always updated with output_token_ids. Having all_token_ids can be useful because we can directly on the entire list of token ids (i.e., prompt_token_ids + output_token_ids) without the O(n) computation every time.

To make sure that the two lists are updated atomically, the PR introduces ConstantList. The constant list provides an immutable view of the list with O(1) overheads.

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

  • Add ready label to the PR
  • Enable auto-merge.

🚀

len is supported by ConstantList, but I fixed this for clarity.
