Struct RunEndArray

pub struct RunEndArray { /* private fields */ }

Implementations

impl RunEndArray

pub fn try_new(ends: ArrayRef, values: ArrayRef) -> VortexResult<Self>

pub fn find_physical_index(&self, index: usize) -> VortexResult<usize>

Convert the given logical index to an index into the values array

pub fn encode(array: ArrayRef) -> VortexResult<Self>

Run the array through run-end encoding.

pub fn offset(&self) -> usize

The offset that the ends is relative to.

This is generally zero for a “new” array, and non-zero after a slicing operation.

pub fn ends(&self) -> &ArrayRef

The encoded “ends” of value runs.

The i-th element indicates that there is a run of the same value, beginning at ends[i] (inclusive) and terminating at ends[i+1] (exclusive).

pub fn values(&self) -> &ArrayRef

The scalar values.

The i-th element is the scalar value for the i-th repeated run. The run begins at ends[i] (inclusive) and terminates at ends[i+1] (exclusive).
