Struct orx_selfref_col::NodeIdx

pub struct NodeIdx<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>) -> Self

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.

Trait Implementations

impl<V: Variant> Clone for NodeIdx<V>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Variant> Debug for NodeIdx<V>

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

Formats the value using the given formatter.

impl<V: Variant> PartialEq for NodeIdx<V>

fn eq(&self, other: &Self) -> bool

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

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

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