rust: exposing in parsers module
To build with the Rust code, set the HGWITHRUSTEXT
environment variable.
At this point, it's possible to instantiate and use
a rustlazyancestors object from a Python interpreter.
The changes in setup.py are obviously a quick hack,
just good enough to test/bench without much
refactoring. We'd be happy to improve on that with
help from the community.
Rust bindings crate gets compiled as a static library,
which in turn gets linked within 'parsers.so'
With respect to the plans at
https://www.mercurial-scm.org/wiki/OxidationPlan
this would probably qualify as "roll our own FFI".
Also, it doesn't quite meet the target of getting
rid of C code, since it brings actually more, yet:
- the new C code does nothing else than parsing
arguments and calling Rust functions.
In particular, there's no complex allocation involved.
- subsequent changes could rewrite more of revlog.c, this
time resulting in an overall decrease of C code and
unsafety.
