Struct json_feed_model::ItemMut

pub struct ItemMut<'a> { /* fields omitted */ }

An Item implemented with a borrowed mutable reference to a JSON object.

Implementations

impl<'a> ItemMut<'a>

pub fn as_map(&self) -> &Map<String, Value>

Returns the inner Map as a reference.

impl<'a> ItemMut<'a>

pub fn as_map_mut(&mut self) -> &mut Map<String, Value>

Returns the inner Map as a mutable reference.

pub fn to_item(&self) -> Item

Clones the inner Map reference and returns an owned type.

pub fn id(&self) -> Result<Option<&str>, Error>

A required unique identifier for an item.

Important

The ID should be unique across all items which have ever appeared in the feed. An item with the same exact ID as another item (even if it is no longer in the current JSON feed items array) are considered the same item.

Version 1.0 Incompatibility

While JSON Feed 1.0 permitted values which could be coerced into JSON strings (e.g. JSON numbers), this model supports only JSON strings. JSON Feed 1.1 strongly suggests to only use strings. In practice, the vast majority of feeds use strings.

If you wish to support non-String IDs, you can directly access the underlying Map with as_map_mut or an equivalent method and read the JSON value.

    T: ToString,

Removes the ID.
