In this case it's required that it manages to + spawn its own threads to parallelize the work it has. + - <csr-id-0fa04bcbdf3102c5435e64cfef894a1bfc8d6e7b/> make current thread-count accessible in slice-workers. + Threads started for working on an entry in a slice can now see the amount + of threads left for use (and manipulate that variable) which effectively + allows them to implement their own parallelization on top of the current one. + + This is useful if there is there is very imbalanced work within the slice itself. + + While at it, we also make consumer functions mutable as they exsit per thread. + +### Commit Statistics + +<csr-read-only-do-not-edit/> + + - 28 commits contributed to the release over the course of 25 calendar days. + - 40 days passed between releases. + - 7 commits were understood as [conventional](https://www.conventionalcommits.org). + - 1 unique issue was worked on: [#851](https://github.com/Byron/gitoxide/issues/851) + +### Thanks Clippy + +<csr-read-only-do-not-edit/> + +[Clippy](https://github.com/rust-lang/rust-clippy) helped 1 time to make code idiomatic. + +### Commit Details + +<csr-read-only-do-not-edit/> + +<details><summary>view details</summary> + + * **[#851](https://github.com/Byron/gitoxide/issues/851)** + - Fix performance regression in pack traversal ([`de1f6c2`](https://github.com/Byron/gitoxide/commit/de1f6c22dfccf22f34e2c2c1b4890ca095ced7ac)) + - Index-backed tree traversal with a form of work-stealing.
