説明

We currently have with_min_len and with_max_len to control the length of the split iterators. However, this only works on an IndexedParallelIterator that knows its length in the first place.

Perhaps we could offer different controls for the splitting depth, or the number of jobs (~2depth), which could work on any parallel iterator. This may line up more directly to how folks think about their tasks, especially if they want to split exactly into the number of threads.

調査方針: Examine the implementation of `with min len` and `with max len` in the Rayon source (likely in `src/iter/plumbing.rs` or similar). Understand how splitting currently works for non indexed iterators. Consider the design of a new method to control splitting depth, potentially by adding a parameter to the `splitter` or `producer` traits. Review the two comments on the issue for additional context.
