Required Methods§

source

fn dtype(&self) -> &DataType

Get data type of ChunkedArray.

source

fn cast(&self, dtype: &DataType) -> Result<Series, PolarsError>

Provided Methods§

source

fn get_any_value(&self, _i: usize) -> Result<AnyValue<'_>, PolarsError>

Gets AnyValue from LogicalType

source

unsafe fn get_any_value_unchecked(&self, _i: usize) -> AnyValue<'_>

§Safety

Does not do any bound checks.
