Struct datafusion::common::arrow::row::Rows

pub struct Rows { /* private fields */ }

A row-oriented representation of arrow data, that is normalized for comparison.

See the module level documentation and RowConverter for more details.

Implementations

impl Rows

pub fn push(&mut self, row: Row<'_>)

Append a Row to this Rows

pub fn row(&self, row: usize) -> Row<'_>

Returns the row at index row

pub unsafe fn row_unchecked(&self, index: usize) -> Row<'_>

Returns the row at index without bounds checking

Safety

Caller must ensure that index is less than the number of offsets (#rows + 1)

pub fn clear(&mut self)

Sets the length of this Rows to 0

pub fn num_rows(&self) -> usize

Returns the number of Row in this Rows

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

Returns an iterator over the Row in this Rows

pub fn size(&self) -> usize

Returns the size of this instance in bytes

Includes the size of Self.

Trait Implementations

impl Debug for Rows

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a Rows

type Item = Row<'a>

The type of the elements being iterated over.

type IntoIter = RowsIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a Rows as IntoIterator>::IntoIter

Creates an iterator from a value.
