Struct listinfo::SubEntry

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

The contents of a sub-entry (such as rom or disk) that is a child of a ListInfo entry.

Sub-entries can not contain their own sub-entries and can only contain scalars or lists of scalars. For example, the rom entries in the following fragment are sub-entries.

game (
 rom (name "Rom 1")
 rom (name "Rom 2")
)

Implementations

impl<'a> SubEntry<'a>

pub fn value(&'a self, key: &str) -> Option<&'a Node<&'a str>>

Retrieves the value of an item data value in the sub-entry.

pub fn value_unique(&'a self, key: &str) -> Option<&'a str>

Gets the entry node with the given key if it exists.

This is shorthand for subentry.value("key").map(|f| f.unique().as_ref())

pub fn value_iter(&'a self, key: &str) -> Option<impl Iterator<Item = &'a str>>

Gets the values with the given key if it exists.

This is shorthand for fragment.value("key").map(|f| f.iter().map(|&s| s))

pub fn iter(&'a self) -> EntryIter<'a, &'a str, Node<&'a str>>

Gets a key value iterator over the values of this fragment.
