Struct tiny_ecs::MapRefMut

pub struct MapRefMut<'a, T> { /* fields omitted */ }

Mutbale reference container for ComponentMap

Methods from Deref<Target = ComponentMap<T>>

pub fn get_part_ref(&self, id: usize) -> Result<&T, ECSError>

Getting a reference to an entity part requires the entity ID

pub fn get_part_mut(&mut self, id: usize) -> Result<&mut T, ECSError>

Getting a mutable reference to an entity part requires the entity ID

Example

#[derive(Debug, PartialEq)]
struct Test1 {}

let components = entities.borrow::<Test1>().unwrap();
let part = components.get_part_ref(entity_1).unwrap();
assert_eq!(part, &Test1 {});
// or
let part = components.get_part_ref(entity_1).unwrap();
assert_eq!(part, &Test1 {});

pub fn get(&self) -> &VecMap<T>

Returns a borrow of the inner hashmap of components

pub fn get_mut(&mut self) -> &mut VecMap<T>

Returns a mutable borrow of the inner hashmap of components
