rust: new rust options in setup.py...
rust: new rust options in setup.py The --rust global option turns on usage (and by default compilation) of the rust-cpython based mercurial.rustext. Similarly to what's previously done for zstd, there is a --no-rust option for the build_ext subcommand in order not to build mercurial.rustext, allowing for an OS distribution to prebuild it. The HGWITHRUSTEXT environment variable is still honored, and has the same effect as before, but now it works mostly by making the --rust global option defaulting to True, with some special cases for the direct-ffi case (see more about that below) Coincidentally, the --rust flag can also be passed from the make commands, like actually all global options, in the PURE variable make local PURE=--rust This feels inappropriate, though, and we should follow up with a proper make variable for that case. Although the direct-ffi bindings aren't directly useful any more, we keep them at this stage because - they provide a short prototyping path for experiments in which a C extension module has to call into a Rust extension. The proper way of doing that would be to use capsules, and it's best to wait for our pull request onto rust-cpython for that: https://github.com/dgrunwald/rust-cpython/pull/169 - Build support for capsules defined in Rust will probably need to reuse some of what's currently in use for direct-ffi.
