Struct ComponentContainer

pub struct ComponentContainer<Id: Hash + Eq, V> { /* private fields */ }

Implementations

impl<Id: Hash + Eq + Copy + Debug, V: Clone> ComponentContainer<Id, V>

pub fn new() -> Self

pub fn get_opt(&self, id: Id) -> Option<&V>

pub fn get(&self, id: Id) -> &V

Note: panics if there’s no such entity.

pub fn get_opt_mut(&mut self, id: Id) -> Option<&mut V>

pub fn get_mut(&mut self, id: Id) -> &mut V

Note: panics if there’s no such entity.

pub fn insert(&mut self, id: Id, data: V)

Store a given data value under a given entity id of a stupid component if no value is already stored under that entity’s id.

pub fn remove(&mut self, id: Id)

Note: panics if there’s no such entity.

pub fn ids(&self) -> IdIter<'_, Id, V>

pub fn ids_collected(&self) -> Vec<Id>

Note: Allocates Vec in heap.
