Functions to implement after rewrite

Once the rewritten package is definitively moved here, we'll be able to focus on implementing relatively new functions:

• Expr:

  • arr.agg()
  • arr.len()
  • arr.eval()
  • bin.reinterpret(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.bin.reinterpret.html#polars.Expr.bin.reinterpret
  • dt.days_in_month()
  • dt.is_business_day()
  • dt.millenium(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.dt.millennium.html#polars.Expr.dt.millennium
  • dt.replace(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.dt.replace.html#polars.Expr.dt.replace
  • index_of(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.index_of.html#polars.Expr.index_of
  • item()
  • min_by
  • max_by
  • list.agg()
  • meta.is_literal(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.meta.is_literal.html#polars.Expr.meta.is_literal
  • name.replace()
  • rolling_rank()
  • rolling_rank_by()
  • rolling_kurtosis()
  • str.escape_regex(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.str.escape_regex.html#polars.Expr.str.escape_regex
  • str.find_many(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.str.find_many.html#polars.Expr.str.find_many
  • str.normalize(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.str.normalize.html#polars.Expr.str.normalize

• Datatype:

  • pl.dtype_of(): https://docs.pola.rs/api/python/dev/reference/datatype_expr/api/polars.dtype_of.html
  • to_dtype_expr(): https://docs.pola.rs/api/python/dev/reference/datatype_expr/api/polars.DataType.to_dtype_expr.html

• DataFrame/LazyFrame:

  • hstack(): https://docs.pola.rs/api/python/dev/reference/dataframe/api/polars.DataFrame.hstack.html#polars.DataFrame.hstack
  • show_graph(): https://docs.pola.rs/api/python/dev/reference/lazyframe/api/polars.LazyFrame.show_graph.html#polars.LazyFrame.show_graph
  • vstack(): https://docs.pola.rs/api/python/dev/reference/dataframe/api/polars.DataFrame.vstack.html#polars.DataFrame.vstack
  • upsample(): https://docs.pola.rs/api/python/dev/reference/dataframe/api/polars.DataFrame.upsample.html#polars.DataFrame.upsample
  • match_to_schema(): https://docs.pola.rs/api/python/dev/reference/dataframe/api/polars.DataFrame.match_to_schema.html#polars.DataFrame.match_to_schema
  • pipe_with_schema()

• I/O:

  • pl.read_parquet_metadata()
  • pl.read_parquet_schema()

• Other:

  • pl.collect_all(): https://docs.pola.rs/api/python/dev/reference/api/polars.collect_all.html#polars.collect_all
  • pl.concat_arr()
  • pl.corr()
  • pl.cov()
  • pl.escape_regex(): https://docs.pola.rs/api/python/dev/reference/api/polars.escape_regex.html#polars.escape_regex Etienne: don't see the point of this function and it's badly documented.
  • pl.explain_all()
  • pl.linear_space(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.linear_space.html#polars.linear_space
  • pl.linear_spaces(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.linear_spaces.html
  • pl.union()

• GroupBy:

  • len(): https://docs.pola.rs/api/python/dev/reference/dataframe/api/polars.dataframe.group_by.GroupBy.len.html#polars.dataframe.group_by.GroupBy.len
  • having()

We probably want to wait to get more information on the new Categoricals before implementing those:

• cat.starts_with(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.cat.starts_with.html
• cat.ends_with(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.cat.ends_with.html
• cat.len_bytes(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.cat.len_bytes.html#polars.Expr.cat.len_bytes
• cat.len_chars(): https://docs.pola.rs/api/python/dev/reference/expressions/api/polars.Expr.cat.len_chars.html#polars.Expr.cat.len_chars
