Struct bevy_ecs::Resources

pub struct Resources { /* fields omitted */ }

A collection of resource instances identified by their type.

Implementations

impl Resources

pub fn insert<T: Resource>(&mut self, resource: T)

pub fn insert_thread_local<T: 'static>(&mut self, resource: T)

pub fn contains<T: Resource>(&self) -> bool

pub fn get<T: Resource>(&self) -> Option<Ref<'_, T>>

pub fn get_mut<T: Resource>(&self) -> Option<RefMut<'_, T>>

pub fn get_thread_local<T: 'static>(&self) -> Option<ResourceRef<'_, T>>

pub fn get_thread_local_mut<T: 'static>(&self) -> Option<ResourceRefMut<'_, T>>

pub fn get_or_insert_with<T: Resource>(
    &mut self,
    get_resource: impl FnOnce() -> T
) -> RefMut<'_, T>

pub fn get_cloned<T: Resource + Clone>(&self) -> Option<T>

Returns a clone of the underlying resource, this is helpful when borrowing something cloneable (like a task pool) without taking a borrow on the resource map

pub fn get_local<'a, T: Resource>(&'a self, id: SystemId) -> Option<Ref<'a, T>>

pub fn get_local_mut<'a, T: Resource>(
    &'a self,
    id: SystemId
) -> Option<RefMut<'a, T>>

pub fn insert_local<T: Resource>(&mut self, id: SystemId, resource: T)

pub fn query<Q: ResourceQuery>(
    &self
) -> Option<<Q::Fetch as FetchResource<'_>>::Item>

pub fn query_system<Q: ResourceQuery>(
    &self,
    id: SystemId
) -> Option<<Q::Fetch as FetchResource<'_>>::Item>

pub unsafe fn get_unsafe_ref<T: Resource>(
    &self,
    resource_index: ResourceIndex
) -> NonNull<T>

pub unsafe fn get_unsafe_ref_with_type_state<T: Resource>(
    &self,
    resource_index: ResourceIndex
) -> (NonNull<T>, &TypeState)

pub unsafe fn get_unsafe_added_and_mutated<T: Resource>(
    &self,
    resource_index: ResourceIndex
) -> (NonNull<bool>, NonNull<bool>)

pub fn borrow<T: Resource>(&self)

pub fn release<T: Resource>(&self)

pub fn borrow_mut<T: Resource>(&self)

pub fn release_mut<T: Resource>(&self)

pub fn clear_trackers(&mut self)

Clears each resource's tracker state. For example, each resource's component "mutated" state will be reset to false.
