Implementations

impl Config

pub fn reload_env_vars(&self)

Reload the config from all environment variables.

pub fn reload_env_var(&self, var: &str)

Reload a specific environment variable.

pub fn verbose(&self) -> bool

Whether we should do verbose printing.

pub fn warn_unstable(&self) -> bool

Whether we should warn when unstable features are used.

pub fn max_threads(&self) -> usize

The number of threads Polars should ideally use for CPU-intensive work.

pub fn ideal_morsel_size(&self) -> u64

The ideal size of a morsel, in rows.

pub fn engine_affinity(&self) -> Engine

Which engine to use by default.

pub fn parquet_binary_statistics_truncate_length(&self) -> u64

Target byte length to truncate statistics to for binary/string columns in parquet.

pub fn prune_parquet_metadata(&self) -> bool

Whether the optimizer should prune parquet metadata to projected/predicate columns before serializing the IR plan. See parquet_metadata_prune in polars-plan.
