Trait polars::prelude::SlicedArray

pub trait SlicedArray {
    // Required methods
    fn slice_typed(&self, offset: usize, length: usize) -> Self
       where Self: Sized;
    unsafe fn slice_typed_unchecked(&self, offset: usize, length: usize) -> Self
       where Self: Sized;
}

Utility trait to slice concrete arrow arrays whilst keeping their concrete type. E.g. don’t return Box<dyn Array>.

Required Methods

fn slice_typed(&self, offset: usize, length: usize) -> Self

where Self: Sized,

Slices this [Array].

Implementation

This operation is O(1) over len.

Panic

This function panics iff offset + length > self.len().

unsafe fn slice_typed_unchecked(&self, offset: usize, length: usize) -> Self

where Self: Sized,

Slices the [Array].

Implementation

This operation is O(1).

Safety

The caller must ensure that offset + length <= self.len()

Implementors
