default = all

we cannot conditionally activate simd https://github.com/rust-lang/cargo/issues/1197 so we have an indirection and compile with --no-default-features --features=all for targets without simd

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

polars-parquet parquet?

arboard clipboard?

serde_json json?
