Available on crate feature object only.

This trait can be registered, after which that global registration can be used to materialize object types

Required Methods

fn append_null(&mut self)

Append a null value.

fn append_value(&mut self, value: &dyn Any)

Append a T of ObjectChunked<T> made generic via the Any trait.

fn to_series(&mut self) -> Series

Take the current state and materialize as a Series the builder should not be used after that.

fn get_list_builder( &self, name: PlSmallStr, values_capacity: usize, list_capacity: usize, ) -> Box<dyn ListBuilderTrait>

Provided Methods

fn append_option(&mut self, value: Option<&dyn Any>)
