Struct ArrowChunk 

pub struct ArrowChunk { /* private fields */ }

A chunk of rows from Arrow data, analogous to TCP’s row chunks.

Implementations

impl ArrowChunk

pub fn len(&self) -> usize

Returns the number of rows in this chunk.

pub fn is_empty(&self) -> bool

Returns true if this chunk has no rows.

pub fn column_count(&self) -> usize

Returns the number of columns.

pub fn row(&self, index: usize) -> Option<ArrowRow<'_>>

Gets the row at the given index.

pub fn first(&self) -> Option<ArrowRow<'_>>

Returns the first row, if any.

pub fn iter(&self) -> ArrowChunkIter<'_>

Returns an iterator over the rows.

pub fn into_batch(self) -> RecordBatch

Consumes the chunk and returns the underlying RecordBatch.

Trait Implementations

impl Debug for ArrowChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a ArrowChunk

type Item = ArrowRow<'a>

The type of the elements being iterated over.

type IntoIter = ArrowChunkIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter
