pub struct WorldCell<'w> { /* private fields */ }
Expand description
Exposes safe mutable access to multiple resources at a time in a World. Attempting to access World in a way that violates Rust’s mutability rules will panic thanks to runtime checks.
Implementations§
source§impl<'w> WorldCell<'w>
impl<'w> WorldCell<'w>
sourcepub fn get_resource<T: Resource>(&self) -> Option<WorldBorrow<'_, T>>
pub fn get_resource<T: Resource>(&self) -> Option<WorldBorrow<'_, T>>
Gets a reference to the resource of the given type
sourcepub fn resource<T: Resource>(&self) -> WorldBorrow<'_, T>
pub fn resource<T: Resource>(&self) -> WorldBorrow<'_, T>
Gets a reference to the resource of the given type
Panics
Panics if the resource does not exist. Use get_resource
instead
if you want to handle this case.
sourcepub fn get_resource_mut<T: Resource>(&self) -> Option<WorldBorrowMut<'_, T>>
pub fn get_resource_mut<T: Resource>(&self) -> Option<WorldBorrowMut<'_, T>>
Gets a mutable reference to the resource of the given type
sourcepub fn resource_mut<T: Resource>(&self) -> WorldBorrowMut<'_, T>
pub fn resource_mut<T: Resource>(&self) -> WorldBorrowMut<'_, T>
Gets a mutable reference to the resource of the given type
Panics
Panics if the resource does not exist. Use get_resource_mut
instead if you want to handle this case.
sourcepub fn get_non_send_resource<T: 'static>(&self) -> Option<WorldBorrow<'_, T>>
pub fn get_non_send_resource<T: 'static>(&self) -> Option<WorldBorrow<'_, T>>
Gets an immutable reference to the non-send resource of the given type, if it exists.
sourcepub fn non_send_resource<T: 'static>(&self) -> WorldBorrow<'_, T>
pub fn non_send_resource<T: 'static>(&self) -> WorldBorrow<'_, T>
Gets an immutable reference to the non-send resource of the given type, if it exists.
Panics
Panics if the resource does not exist. Use
get_non_send_resource
instead if you want to handle
this case.
sourcepub fn get_non_send_resource_mut<T: 'static>(
&self
) -> Option<WorldBorrowMut<'_, T>>
pub fn get_non_send_resource_mut<T: 'static>( &self ) -> Option<WorldBorrowMut<'_, T>>
Gets a mutable reference to the non-send resource of the given type, if it exists.
sourcepub fn non_send_resource_mut<T: 'static>(&self) -> WorldBorrowMut<'_, T>
pub fn non_send_resource_mut<T: 'static>(&self) -> WorldBorrowMut<'_, T>
Gets a mutable reference to the non-send resource of the given type, if it exists.
Panics
Panics if the resource does not exist. Use
get_non_send_resource_mut
instead if you want to
handle this case.
sourcepub fn send_event<E: Event>(&self, event: E)
pub fn send_event<E: Event>(&self, event: E)
Sends an Event
.
sourcepub fn send_event_default<E: Event + Default>(&self)
pub fn send_event_default<E: Event + Default>(&self)
Sends the default value of the Event
of type E
.
sourcepub fn send_event_batch<E: Event>(&self, events: impl Iterator<Item = E>)
pub fn send_event_batch<E: Event>(&self, events: impl Iterator<Item = E>)
Sends a batch of Event
s from an iterator.
