Struct ComponentMap 

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

A JS object { [c in Component]?: number }, keeping insertion order like JS does.

Implementations

impl ComponentMap

pub fn new() -> ComponentMap

pub fn from_pairs(pairs: &[(Component, i64)]) -> ComponentMap

pub fn get(&self, c: Component) -> Option<i64>

pub fn contains(&self, c: Component) -> bool

pub fn set(&mut self, c: Component, v: i64)

Assignment keeps an existing key’s position, like a JS object.

pub fn remove(&mut self, c: Component)

pub fn keys(&self) -> impl Iterator<Item = Component> + '_

pub fn iter(&self) -> impl Iterator<Item = (Component, i64)> + '_

pub fn is_empty(&self) -> bool
