Enum yaml_peg::serde::InlineList

pub enum InlineList<T> {
    List(Vec<T>),
    Inline(T),
}

Available on crate feature serde only.

A data type that can support listed items, or inline it if there is single item.

use serde::Deserialize;
use yaml_peg::{node, serde::InlineList};

#[derive(Deserialize)]
struct Content {
    img: InlineList<Img>,
}

#[derive(Deserialize)]
struct Img {
    src: String,
}

let n_listed = node!({"img" => node!([node!({"src" => "img/1.png"}), node!({"src" => "img/2.png"})])});
let n_inline = node!({"img" => node!({"src" => "img/1.png"})});
let listed = Content::deserialize(n_listed).unwrap();
let inline = Content::deserialize(n_inline).unwrap();
for (i, img) in listed.img.iter().enumerate() {
    assert_eq!(format!("img/{}.png", i + 1), img.src);
}
for (i, img) in inline.img.into_iter().enumerate() {
    assert_eq!(format!("img/{}.png", i + 1), img.src);
}

Variants

List(Vec<T>)

Listed representation.

Inline(T)

Inline representation.

Implementations

impl<T> InlineList<T>

pub fn iter(&self) -> Iter<'_, T>

Return the iterator over the items.

pub fn len(&self) -> usize

Get the length of the list.

pub fn is_empty(&self) -> bool

Return true if the list is empty.

pub fn is_single(&self) -> bool

Return true if the list has only one item.

Trait Implementations

impl<T: Debug> Debug for InlineList<T>

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

Formats the value using the given formatter.

impl<T> Default for InlineList<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for InlineList<T> where
    T: Deserialize<'de>, 

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<T> IntoIterator for InlineList<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = <Vec<T, Global> as IntoIterator>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: PartialEq> PartialEq<InlineList<T>> for InlineList<T>

fn eq(&self, other: &InlineList<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> Serialize for InlineList<T> where
    T: Serialize, 

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
