Struct parquet::record::Map

pub struct Map { /* private fields */ }

Map represents a map which contains a list of key->value pairs.

Implementations

impl Map

pub fn len(&self) -> usize

Get the number of fields in this row

pub fn entries(&self) -> &[(Field, Field)]

Get the reference to the key-value pairs in this map

Trait Implementations

impl Clone for Map

fn clone(&self) -> Map

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Map

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

Formats the value using the given formatter.

impl MapAccessor for Map

fn get_keys<'a>(&'a self) -> Box<dyn ListAccessor + 'a>

Get the keys of the map.

fn get_values<'a>(&'a self) -> Box<dyn ListAccessor + 'a>

Get the values of the map.

impl PartialEq for Map

fn eq(&self, other: &Map) -> 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.
