## Summary This PR removes the custom `DistFinder` that we use in `pip sync`. This originally existed because `VersionMap` wasn't lazy, and so we saved a lot of time in `DistFinder` by reading distribution data lazily. But now, AFAICT, there's really no benefit. Maintaining `DistFinder` means we effectively have to maintain two resolvers, and end up fixing bugs in `DistFinder` that don't exist in the `Resolver` (like #2688. Closes #2694. Closes #2443. ## Test Plan I ran this benchmark a bunch. It's basically a wash. Sometimes one is faster than the other. ``` ❯ python -m scripts.bench \ --uv-path ./target/release/main \ --uv-path ./target/release/uv \ scripts/requirements/compiled/trio.txt --min-runs 50 --benchmark install-warm --warmup 25 Benchmark 1: ./target/release/main (install-warm) Time (mean ± σ): 54.0 ms ± 10.6 ms [User: 8.7 ms, System: 98.1 ms] Range (min … max): 45.5 ms … 94.3 ms 50 runs Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet PC without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options. Benchmark 2: ./target/release/uv (install-warm) Time (mean ± σ): 50.7 ms ± 9.2 ms [User: 8.7 ms, System: 98.6 ms] Range (min … max): 44.0 ms … 98.6 ms 50 runs Warning: The first benchmarking run for this command was significantly slower than the rest (77.6 ms). This could be caused by (filesystem) caches that were not filled until after the first run. You should consider using the '--warmup' option to fill those caches before the actual benchmark. Alternatively, use the '--prepare' option to clear the caches before each timing run. Summary './target/release/uv (install-warm)' ran 1.06 ± 0.29 times faster than './target/release/main (install-warm)' ``` |

Reimplementation of wheel installing in rust. Supports both classical venvs and monotrail.
There are simple python bindings:
from install_wheel_rs import LockedVenv
locked_venv = LockedVenv("path/to/.venv")
locked_venv.install_wheel("path/to/some_tagged_wheel.whl")
and there's only one function: install_wheels_venv(wheels: List[str], venv: str), where wheels is a list of paths to wheel files and venv is the location of the venv to install the packages in.
See monotrail for benchmarks.
