Replying to myself and thinking out loud, one thing really saved me a ton of hassle in a recent project was leaning on DataFrames because they align really well with SQL tables and also can save you from needing to make new data structures; especially in Rust, making new “classes” can be tremendously time consuming, reusing Series with a different dtype might save bevy users from needing to impl X for Y a billion different times to make a new struct Y. Series already has implementations for whatever is needed. It’s too bad Polars separates Row from Series so hard in the type system, because this is the true 100x gain of Pandas: evading the OOP paradigm with thing_ser and things_df instead of class Thing and Tuple[Thing, …] I.E. instead of forcing Bevy devs to pass around these heinous Query, Query, Query signatures and remember the order, maybe a “creatures_df” with appropriate columns would be more fun to work with because it’s a bit higher level but still performant (and possibly less code to maintain by pushing work onto Polars) More focus on polars row feature imho is needed for the rust community to thrive, it’s a backwater in that workspace which could become a saving grace Edit: also, an easy compilation gain is to… # Parallelize Rustc: https://blog.rust-lang.org/2023/11/09/parallel-rustc.html https://blog.rust-lang.org/2023/11/09/parallel-rustc.html Makefile: RUSTFLAGS_VALUES = "-Z threads=8" test: test-stable .PHONY: test-nightly test-nightly: RUSTFLAGS=$(RUSTFLAGS_VALUES) cargo +nightly nextest run .PHONY: test-docs test-docs: RUSTFLAGS=$(RUSTFLAGS_VALUES) cargo +nightly test --doc .PHONY: test-stable test-stable: cargo test cfg: RUSTFLAGS=$(RUSTFLAGS_VALUES) cargo +nightly -Z unstable-options rustc --print cfg # Run tests and benchmarks every time a file changes watch-nightly: RUSTFLAGS=$(RUSTFLAGS_VALUES) cargo +nightly watch -x "nextest run" -x "test --doc"
