Struct bevy::ecs::reflect::ReflectResource
[−]pub struct ReflectResource { /* private fields */ }
Expand description
A struct used to operate on reflected Resource
of a type.
A ReflectResource
for type T
can be obtained via
[bevy_reflect::TypeRegistration::data
].
Implementations
impl ReflectResource
impl ReflectResource
pub fn apply_or_insert(
&self,
world: &mut World,
resource: &(dyn Reflect + 'static)
)
pub fn apply_or_insert(
&self,
world: &mut World,
resource: &(dyn Reflect + 'static)
)
Uses reflection to set the value of this Resource
type in the world to the given value or insert a new one if it does not exist.
pub fn remove(&self, world: &mut World)
pub fn remove(&self, world: &mut World)
Removes this Resource
type from the world. Does nothing if it doesn’t exist.
pub fn reflect(&self, world: &'a World) -> Option<&'a (dyn Reflect + 'static)>
pub fn reflect(&self, world: &'a World) -> Option<&'a (dyn Reflect + 'static)>
Gets the value of this Resource
type from the world as a reflected reference.
pub fn reflect_mut(&self, world: &'a mut World) -> Option<ReflectMut<'a>>
pub fn reflect_mut(&self, world: &'a mut World) -> Option<ReflectMut<'a>>
Gets the value of this Resource
type from the world as a mutable reflected reference.
pub unsafe fn reflect_unchecked_mut(
&self,
world: &'a World
) -> Option<ReflectMut<'a>>
pub unsafe fn reflect_unchecked_mut(
&self,
world: &'a World
) -> Option<ReflectMut<'a>>
Safety
This method does not prevent you from having two mutable pointers to the same data, violating Rust’s aliasing rules. To avoid this:
- Only call this method in an exclusive system to avoid sharing across threads (or use a scheduler that enforces safe memory access).
- Don’t call this method more than once in the same scope for a given
Resource
.
