Enum listinfo::Node

pub enum Node<T> {
    Unique(T),
    Many(Vec<T>),
}

Represents nodes with the given key in an ListInfo entry.

The split between Unique and Many is mostly for performance reasons to avoid unnecessary allocations. Node::Unique appeared exactly once in the parsed DAT file, while Node::Unique appeared more than once.

Instead of accessing the enum members directly, the Node::iter and Node::unique methods abstract over the difference between Unique and Many for convenience.

Variants

Unique(T)

A uniquely keyed node (only one of such key exists in the entry)

Many(Vec<T>)

Multiple nodes with the same key.

Implementations

impl<'a, T> Node<T>

pub fn iter(&'a self) -> NodeIter<'a, T>

Gets the values with the given key.

If the provided key is a unique value, returns an iterator that yields that single value.

pub fn unique(&'a self) -> &'_ T

Gets a single value with the given key.

If the provided key is not unique, retrieves the first value of the many-set with the given key.
