Struct WidgetNodeId 

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

A 128-bit identity for a widget.

Like NodeId, this is derived from a BLAKE3 hash, but it uses the "widget:" prefix so that widget IDs and node IDs never collide. Widget IDs are interconvertible with node IDs via From impls.

Example

use fission_ir::WidgetNodeId;
let wid = WidgetNodeId::explicit("video-player");

Implementations

impl WidgetNodeId

pub const fn from_u128(val: u128) -> WidgetNodeId

Creates a WidgetNodeId from a raw 128-bit value.

Intended for internal use or deserialization.

pub fn as_u128(&self) -> u128

Returns the underlying 128-bit value.

pub fn explicit(name: &str) -> WidgetNodeId

Creates a WidgetNodeId from a user-provided name string.

The name is hashed with BLAKE3 (prefixed with "widget:"), producing a deterministic ID. Use this to give stable identities to platform-embedded widgets.

Example

use fission_ir::WidgetNodeId;
let a = WidgetNodeId::explicit("camera-preview");
let b = WidgetNodeId::explicit("camera-preview");
assert_eq!(a, b);

Trait Implementations

impl Clone for WidgetNodeId

fn clone(&self) -> WidgetNodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetNodeId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WidgetNodeId

fn deserialize<__D>( __deserializer: __D, ) -> Result<WidgetNodeId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<NodeId> for WidgetNodeId

fn from(node: NodeId) -> WidgetNodeId

Converts to this type from the input type.

impl From<WidgetNodeId> for NodeId

fn from(id: WidgetNodeId) -> NodeId

Converts to this type from the input type.

impl Hash for WidgetNodeId

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

where __H: Hasher,

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 WidgetNodeId

fn cmp(&self, other: &WidgetNodeId) -> 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 WidgetNodeId

fn eq(&self, other: &WidgetNodeId) -> 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 WidgetNodeId

fn partial_cmp(&self, other: &WidgetNodeId) -> 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.

impl Serialize for WidgetNodeId

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for WidgetNodeId

impl Eq for WidgetNodeId
