Struct tiny_ecs::PartMapRef

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

Methods

impl<'a, T: 'static> PartMapRef<'a, T>

pub fn new(
    value: &'a RefCell<Box<dyn Any>>
) -> Result<PartMapRef<'a, T>, ECSError>

Methods from Deref<Target = PartMap<T>>

pub fn get_part_ref(&self, id: u32) -> Result<&T, &'static str>

pub fn iter_ref(&self) -> Iter<u32, T>

Returns an immutable iterator over the part map

Example

let partmap = entities.get_map_ref::<Test1>()
        .expect("No part found for entity");
for (k, v) in partmap.iter_ref() {
    assert!(v.x == *k);
}

Trait Implementations

impl<'a, T> Deref for PartMapRef<'a, T>

type Target = PartMap<T>

The resulting type after dereferencing.

fn deref(&self) -> &PartMap<T>

Dereferences the value.
