Struct orx_linked_list::NodeIdx

pub struct NodeIdx<V>
where
    V: Variant,
{ /* private fields */ }

A node index providing safe and constant time access to elements of the self referential collection.

Implementations

impl<V> NodeIdx<V>

where V: Variant,

pub fn new(state: MemoryState, node_ptr: &NodePtr<V>) -> NodeIdx<V>

Creates a new index for the element at the given node_ptr and the collection with the given state.

pub fn is_in_state(&self, state: MemoryState) -> bool

Checks whether or not the state of the index matches that of this index.

pub fn get_ptr(&self, collection_state: MemoryState) -> Option<*mut Node<V>>

Returns the node pointer if the index is in the same state as the collection_state, None otherwise.

pub fn node_ptr(&self) -> NodePtr<V>

Converts the node index into a node pointer.

impl<V> PartialEq for NodeIdx<V>

where V: Variant,

fn eq(&self, other: &NodeIdx<V>) -> bool

Tests for self and other values to be equal, and is used by ==.
