Struct TraitMap 

pub struct TraitMap { /* private fields */ }

A map of traits keyed by their Shape ID.

This provides efficient lookup of traits during serialization and deserialization.

Implementations

impl TraitMap

pub fn new() -> Self

Creates a new empty TraitMap.

pub fn insert(&mut self, trait_obj: Box<dyn Trait>)

Inserts a trait into the map.

pub fn get(&self, id: &ShapeId) -> Option<&dyn Trait>

Gets a trait by its Shape ID.

pub fn contains(&self, id: &ShapeId) -> bool

Returns true if the map contains a trait with the given Shape ID.

pub fn iter(&self) -> impl Iterator<Item = (&ShapeId, &dyn Trait)>

Returns an iterator over all traits.

pub fn len(&self) -> usize

Returns the number of traits in the map.

pub fn is_empty(&self) -> bool

Returns true if the map is empty.
