Describe the bug

I just init a project and try to run a example:

cargo init
cargo add RustQuant
cargo run --example yahoo_finance

got this error

error[E0599]: no method named raw_table_mut found for struct hashbrown::HashMap in the current scope

--> /home/allen/.cargo/registry/src/index.crates.io-6f17d22bba15001f/polars-core-0.41.3/src/chunked_array/builder/list/categorical.rs

Same thing for me. It might be related to this Polars issue -> error[E0599]: no method named raw_table_mut found for struct hashbrown::HashMap in the current scope

Disclaimer: [.....] before .cargo is me shortening the output :D

Temporary solution is to downgrade polars?

Thanks for pointing this out. Will publish a temp fix for this shortly.
