Struct NodePtr

pub struct NodePtr<V: Variant> { /* private fields */ }

A wrapper around a node pointer.

Implementations

impl<V: Variant> NodePtr<V>

pub fn new(ptr: *const Node<V>) -> Self

Creates a new node pointer by wrapping the given ptr.

pub fn ptr(&self) -> *const Node<V>

Returns the const raw pointer.

pub fn ptr_mut(&self) -> *mut Node<V>

Returns the mutable raw pointer.

pub unsafe fn node(&self) -> &Node<V>

Returns a reference to the node.

Safety

The caller must ensure that:

• this pointer is created from a self referential collection,
• the collection is still alive, and finally,
• the memory state of the collection has not changed since the pointer was created.

pub unsafe fn node_mut(&self) -> &mut Node<V>

Returns a mutable reference to the node.

Safety

The caller must ensure that:

• this pointer is created from a self referential collection,
• the collection is still alive, and finally,
• the memory state of the collection has not changed since the pointer was created.

Trait Implementations

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

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<V: Variant> PartialEq for NodePtr<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.
