Struct NodeId 

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

A lightweight, interned identifier for nodes in the scene graph. Internally a Spur index — 4 bytes, Copy, Eq, Hash in O(1).

Implementations

impl NodeId

pub fn intern(s: &str) -> Self

Intern a new string as a NodeId, or return existing if already interned.

pub fn as_str(&self) -> &str

Resolve back to a string slice.

pub fn anonymous(kind: &str) -> Self

Generate a unique anonymous ID (for nodes without explicit @id). Uses the node kind as prefix: _rect_0, _text_1, _group_2, etc.

pub fn with_prefix(prefix: &str) -> Self

Generate a unique ID with a type prefix (e.g. rect_1, ellipse_2).

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeId

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

Deserialize this value from the given Serde deserializer.

impl Display for NodeId

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

Formats the value using the given formatter.

impl Hash for NodeId

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 PartialEq for NodeId

fn eq(&self, other: &NodeId) -> 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 Serialize for NodeId

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

Serialize this value into the given Serde serializer.

impl Copy for NodeId

impl Eq for NodeId

impl StructuralPartialEq for NodeId
