Struct AnyValueBufferBatched 

pub struct AnyValueBufferBatched<'a> { /* private fields */ }

Available on crate features object or rows only.

An AnyValueBuffer that converts nested values in batches (as each value retains a Series until finally converted, this can prevent excessive peak memory use).

Implementations

impl<'a> AnyValueBufferBatched<'a>

pub fn new(dtype: &DataType, capacity: usize) -> AnyValueBufferBatched<'a>

pub fn add(&mut self, val: AnyValue<'_>) -> Option<()>

pub fn add_fallible(&mut self, val: &AnyValue<'a>) -> Result<(), PolarsError>

pub fn needs_flush(&self) -> bool

Whether a full batch of nested values is ready to flush.

pub fn flush(&mut self) -> Result<(), PolarsError>

Converts the buffered nested values, extending the converted SeriesBuilder. Frees the memory used by the buffered values.

pub fn into_series(self) -> Result<Series, PolarsError>

pub fn into_column( self, name: PlSmallStr, height: usize, ) -> Result<Column, PolarsError>

Convert into a column of height rows.
