Expand description

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

Required Methods§

source

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

Slices this Array.

Implementation

This operation is O(1) over len.

Panic

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

source

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

Slices the Array.

Implementation

This operation is O(1).

Safety

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