Struct polars_core::series::amortized_iter::AmortSeries

pub struct AmortSeries { /* private fields */ }

A [Series] that amortizes a few allocations during iteration.

Implementations

impl AmortSeries

pub fn new(series: Rc<Series>) -> Self

pub fn deep_clone(&self) -> Series

pub unsafe fn swap(&mut self, array: &mut ArrayRef)

Swaps inner state with the array. Prefer AmortSeries::with_array as this restores the state.

Safety

This swaps an underlying pointer that might be hold by other cloned series.

pub unsafe fn with_array<F, T>(&mut self, array: &mut ArrayRef, f: F) -> T

where F: Fn(&AmortSeries) -> T,

Temporary swaps out the array, and restores the original state when application of the function f is done.

Safety

Array must be from Series physical dtype.

Trait Implementations

impl AsRef<Series> for AmortSeries

We don’t implement Deref so that the caller is aware of converting to Series

fn as_ref(&self) -> &Series

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AmortSeries

fn clone(&self) -> AmortSeries

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
