Struct HandleId 

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

Identifier for a user value T in the binding-side registry.

The Core stores HandleId everywhere user values would otherwise sit: cache, prevData, Data/Error payloads, dep records. Equals-substitution under EqualsMode::Identity compares HandleId directly (a u64 ==).

Implementations

impl HandleId

pub const fn new(raw: u64) -> Self

Wrap a raw u64. Real handles come from the binding-side registry (bindings.ts valueRegistry.intern(value)); this constructor is for tests and FFI round-tripping.

pub const fn raw(self) -> u64

Unwrap to the underlying u64.

pub const fn is_sentinel(self) -> bool

True if this is the NO_HANDLE sentinel (handle id 0 is never assigned to a real value). Equivalent to self == NO_HANDLE.

Trait Implementations

impl Clone for HandleId

fn clone(&self) -> HandleId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleId

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

Formats the value using the given formatter.

impl Display for HandleId

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

Formats the value using the given formatter.

impl Hash for HandleId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for HandleId

fn cmp(&self, other: &HandleId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HandleId

fn eq(&self, other: &HandleId) -> 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 PartialOrd for HandleId

fn partial_cmp(&self, other: &HandleId) -> 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

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