fix pyo3 build thrashing cross-IDE

[andrewgazelka]

or at least let's figure out how we can get pyo3 to stop recompiling all
the time when I am using JetBrains. How did we fix this for VSC?

looks lke we did

/~https://github.com/Eventual-Inc/Daft/blob/main/.vscode/settings.json#L3

however I am confused about details about how this works and if IntelliJ
is what is causing things to recompile for me

for the pyo3 build thrashing, the recommended approach is actually to set the env var PYO3_PYTHON to a hardcoded path. PyO3/pyo3#1708

The vscode settings help with this in a different way, it sets rust-analyzer to use it's own build directory instead of sharing it with ./target, but it solves the same problem as pyo3 is always built with the same env vars

I'm not a jetbrains user, but I'm sure there's likely a way to set their analyzer to use a custom path. Set it to something like ./target/analyzer and that'd be the equivalent of the vscode settings

I personally prefer keeping IDE specific settings out of the core repo, and instead add it to a contributors guide.

perhaps we can set .cargo/config.toml? https://www.perplexity.ai/search/pyo3-python-fix-pyo3-recompile-.8_iGSsmQravJ671YMe5Og#0 just made mine

[env]
PYO3_PYTHON = "./.venv/bin/python"

seems to fix
