Struct SignalIdentity 

pub struct SignalIdentity(/* private fields */);

Stable identity for reactive signal instances that own observable state.

Implementations

impl SignalIdentity

pub fn from_rc<T>(value: &Rc<T>) -> Self

Creates an identity from a shared allocation pointer.

The allocation must be tied to the semantic signal instance and be cloned together with that instance.

pub fn from_ptr<T>(value: *const T) -> Self

Creates an identity from a stable allocation pointer.

Panics

Panics when the pointer is null.

pub const fn raw(self) -> usize

Raw value for renderer-local key composition.

pub const fn with_discriminator(self, discriminator: usize) -> Self

Creates a stable derived identity for a property of this signal.

pub const fn combine(self, other: Self) -> Self

Combines two stable signal identities into one deterministic identity.

pub fn call_site_discriminator<T: 'static>( caller: &'static Location<'static>, ) -> usize

Creates a stable discriminator from a call site and semantic wrapper type.

Trait Implementations

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SignalIdentity

fn partial_cmp(&self, other: &SignalIdentity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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