Struct ReadComponent

pub struct ReadComponent<'a, T: StorageSpec<'a>> { /* private fields */ }

Read-only view of a Component storage.

Implementations

impl<'a, T> ReadComponent<'a, T>

where T: 'a + StorageSpec<'a>, T::Storage: ComponentStorage<'a>,

pub fn get(v: &Self) -> &T::Storage

Get a reference to the underlying Storage. This is an associated method because ReadComponent implements Deref.

Trait Implementations

impl<'a, T> Clone for ReadComponent<'a, T>

where T: 'a + StorageSpec<'a>,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, WD, T> ComponentProviderRec<'a, ReadComponent<'a, T>> for WD

where T: 'a + StorageSpec<'a>, WD: WorldInterface<'a> + GetComponent<'a, T>,

fn fetch(&'a self) -> ReadComponent<'_, T>

Get the components.

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

where T: 'a + StorageSpec<'a>, T::Storage: ComponentStorage<'a>,

type Target = <T as StorageSpec<'a>>::Storage

The resulting type after dereferencing.

fn deref(&self) -> &T::Storage

Dereferences the value.
