rust: hooking into Python code
We introduce a new class called 'rustlazyancestors'
in the ancestors module, which is used only if
parsers.rustlazyancestors does exist.
The implementation of __contains__ stays unchanged,
but is now backed by the Rust iterator. It would
probably be a good candidate for further development,
though, as it is mostly looping, and duplicates the
'seen' set.
The Rust code could be further optimized, however it already
gives rise to performance improvements:
median timing from hg perfancestors:
- on pypy:
before: 0.077566s
after: 0.016676s -79%
- on mozilla central:
before: 0.190037s
after: 0.082225s -58%
- on a private repository (about one million revisions):
before: 0.567085s
after: 0.108816s -80%
- on another private repository (about 400 000 revisions):
before: 1.440918s
after: 0.290116s -80%
median timing for hg perfbranchmap base
- on pypy:
before: 1.383413s
after: 0.507993s -63%
- on mozilla central:
before: 2.821940s

- on a private repository (about one million revisions):
