Implementations

impl Nested

pub fn len(&self) -> usize

Returns the length (number of rows) of the element

pub fn primitive( validity: Option<Bitmap>, is_optional: bool, length: usize, ) -> Self

pub fn list( validity: Option<Bitmap>, is_optional: bool, offsets: OffsetsBuffer<i32>, ) -> Self

pub fn large_list( validity: Option<Bitmap>, is_optional: bool, offsets: OffsetsBuffer<i64>, ) -> Self

pub fn fixed_size_list( validity: Option<Bitmap>, is_optional: bool, width: usize, length: usize, ) -> Self

pub fn structure( validity: Option<Bitmap>, is_optional: bool, length: usize, ) -> Self

Trait Implementations

impl Clone for Nested

fn clone(&self) -> Nested

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Nested

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

Formats the value using the given formatter.

impl PartialEq for Nested

fn eq(&self, other: &Nested) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
