Struct SeriesBuilder

pub struct SeriesBuilder { /* private fields */ }

A type-erased wrapper around ArrayBuilder.

Implementations

impl SeriesBuilder

pub fn new(dtype: DataType) -> SeriesBuilder

pub fn reserve(&mut self, additional: usize)

pub fn freeze(self, name: PlSmallStr) -> Series

pub fn freeze_reset(&mut self, name: PlSmallStr) -> Series

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn extend(&mut self, other: &Series, share: ShareStrategy)

Extends this builder with the contents of the given series. May panic if other does not match the dtype of this builder.

pub fn subslice_extend( &mut self, other: &Series, start: usize, length: usize, share: ShareStrategy, )

Extends this builder with the contents of the given series subslice. May panic if other does not match the dtype of this builder.

pub fn subslice_extend_repeated( &mut self, other: &Series, start: usize, length: usize, repeats: usize, share: ShareStrategy, )

pub unsafe fn gather_extend( &mut self, other: &Series, idxs: &[u32], share: ShareStrategy, )

Extends this builder with the contents of the given series at the given indices. That is, other[idxs[i]] is appended to this builder in order, for each i=0..idxs.len(). May panic if other does not match the dtype of this builder, or if the other series is not rechunked.

Safety

The indices must be in-bounds.
