Struct SExp 

pub struct SExp(pub Sequence);

An in-memory representation of an Ion s-expression

use ion_rs::{Element, ion_sexp};
let sexp = ion_sexp!(1 2 3);
assert_eq!(sexp.len(), 3);
assert_eq!(sexp.get(1), Some(&Element::int(2)));

To build a SExp incrementally, see SequenceBuilder.

The inner Sequence is public to match Value::SExp(Sequence), allowing direct construction and destructuring.

Trait Implementations

impl AsRef<Sequence> for SExp

fn as_ref(&self) -> &Sequence

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

impl AsRef<[Element]> for SExp

fn as_ref(&self) -> &[Element]

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

impl Clone for SExp

fn clone(&self) -> SExp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SExp

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

Formats the value using the given formatter.

impl Display for SExp

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

Formats the value using the given formatter.

impl From<SExp> for Value

fn from(s_expr: SExp) -> Self

Converts to this type from the input type.

impl From<SExp> for Sequence

fn from(value: SExp) -> Self

Converts to this type from the input type.

impl From<Sequence> for SExp

fn from(sequence: Sequence) -> Self

Converts to this type from the input type.

impl From<Vec<Element>> for SExp

fn from(elements: Vec<Element>) -> Self

Converts to this type from the input type.

impl FromIterator<Element> for SExp

fn from_iter<T: IntoIterator<Item = Element>>(iter: T) -> Self

Creates a value from an iterator.

impl<'a> IntoIterator for &'a SExp

type Item = &'a Element

The type of the elements being iterated over.

type IntoIter = SequenceIterator<'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 SExp

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