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
impl<'w> WorldCell<'w>
impl<'w> WorldCell<'w>
pub fn get_resource<T>(&self) -> Option<WorldBorrow<'_, T>> where
T: Resource,
pub fn get_resource<T>(&self) -> Option<WorldBorrow<'_, T>> where
T: Resource,
Gets a reference to the resource of the given type
pub fn resource<T>(&self) -> WorldBorrow<'_, T> where
T: Resource,
pub fn resource<T>(&self) -> WorldBorrow<'_, T> where
T: Resource,
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.
pub fn get_resource_mut<T>(&self) -> Option<WorldBorrowMut<'_, T>> where
T: Resource,
pub fn get_resource_mut<T>(&self) -> Option<WorldBorrowMut<'_, T>> where
T: Resource,
Gets a mutable reference to the resource of the given type
pub fn resource_mut<T>(&self) -> WorldBorrowMut<'_, T> where
T: Resource,
pub fn resource_mut<T>(&self) -> WorldBorrowMut<'_, T> where
T: Resource,
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.
pub fn get_non_send_resource<T>(&self) -> Option<WorldBorrow<'_, T>> where
T: 'static,
pub fn get_non_send_resource<T>(&self) -> Option<WorldBorrow<'_, T>> where
T: 'static,
Gets an immutable reference to the non-send resource of the given type, if it exists.
pub fn non_send_resource<T>(&self) -> WorldBorrow<'_, T> where
T: 'static,
pub fn non_send_resource<T>(&self) -> WorldBorrow<'_, T> where
T: 'static,
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.
pub fn get_non_send_resource_mut<T>(&self) -> Option<WorldBorrowMut<'_, T>> where
T: 'static,
pub fn get_non_send_resource_mut<T>(&self) -> Option<WorldBorrowMut<'_, T>> where
T: 'static,
Gets a mutable reference to the non-send resource of the given type, if it exists.
pub fn non_send_resource_mut<T>(&self) -> WorldBorrowMut<'_, T> where
T: 'static,
pub fn non_send_resource_mut<T>(&self) -> WorldBorrowMut<'_, T> where
T: 'static,
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.
