Struct RcAnchor 

#[repr(transparent)]
pub struct RcAnchor<T: ?Sized>(pub Rc<T>);

Serialization public API is defined at crate root A wrapper around Rc<T> that opt-ins a field for anchor emission (e.g. serialization by reference).

This type behaves like a normal Rc<T> but signals that the value should be treated as an anchorable reference — for instance, when serializing graphs or shared structures where pointer identity matters.

Examples

use std::rc::Rc;
use serde_saphyr::RcAnchor;

// Create from an existing Rc
let rc = Rc::new(String::from("Hello"));
let anchor1 = RcAnchor::from(rc.clone());

// Or directly from a value (Rc::new is called internally)
let anchor2: RcAnchor<String> = RcAnchor::from(Rc::new(String::from("World")));

assert_eq!(*anchor1.0, "Hello");
assert_eq!(*anchor2.0, "World");

Trait Implementations

impl<T: ?Sized> AsRef<Rc<T>> for RcAnchor<T>

fn as_ref(&self) -> &Rc<T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: ?Sized> Borrow<Rc<T>> for RcAnchor<T>

fn borrow(&self) -> &Rc<T>

Immutably borrows from an owned value.

impl<T: Clone + ?Sized> Clone for RcAnchor<T>

fn clone(&self) -> RcAnchor<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> Debug for RcAnchor<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for RcAnchor<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: ?Sized> Deref for RcAnchor<T>

type Target = Rc<T>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de, T> Deserialize<'de> for RcAnchor<T>

where T: Deserialize<'de> + 'static,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: ?Sized> From<&RcAnchor<T>> for RcWeakAnchor<T>

fn from(rca: &RcAnchor<T>) -> Self

Converts to this type from the input type.

impl<T: ?Sized> From<Rc<T>> for RcAnchor<T>

fn from(rc: Rc<T>) -> Self

Converts to this type from the input type.

impl<T: ?Sized> From<RcAnchor<T>> for Rc<T>

fn from(a: RcAnchor<T>) -> Rc<T>

Converts to this type from the input type.

impl<T: ?Sized> PartialEq for RcAnchor<T>

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.

impl<T: Serialize> Serialize for RcAnchor<T>

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<T: ?Sized> Eq for RcAnchor<T>
