Struct List

pub struct List(pub Sequence);

An in-memory representation of an Ion list.

use ion_rs::element::{Element, List};
use ion_rs::ion_list;
let list = ion_list![1, 2, 3];
assert_eq!(list.len(), 3);
assert_eq!(list.get(1), Some(&Element::integer(2)));

To build a List incrementally, see SequenceBuilder.

Implementations

impl List

pub fn clone_builder(&self) -> SequenceBuilder

pub fn elements(&self) -> ElementsIterator<'_>

pub fn get(&self, index: usize) -> Option<&Element>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl AsRef<Sequence> for List

fn as_ref(&self) -> &Sequence

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for List

fn clone(&self) -> List

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for List

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

Formats the value using the given formatter.

impl Display for List

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

Formats the value using the given formatter.

impl From<List> for Sequence

fn from(value: List) -> Self

Converts to this type from the input type.

impl From<List> for Value

fn from(list: List) -> Self

Converts to this type from the input type.

impl From<Sequence> for List

fn from(sequence: Sequence) -> Self

Converts to this type from the input type.

impl<'a> IntoIterator for &'a List

type Item = &'a Element

The type of the elements being iterated over.

type IntoIter = ElementsIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for List

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

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

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

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

impl Eq for List

impl StructuralPartialEq for List
