Struct bevy_ecs::reflect::ReflectResource
source · pub struct ReflectResource(_);
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§
source§impl ReflectResource
impl ReflectResource
sourcepub fn apply_or_insert(&self, world: &mut World, resource: &dyn Reflect)
pub fn apply_or_insert(&self, world: &mut World, resource: &dyn Reflect)
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.
sourcepub 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.
sourcepub fn reflect<'a>(&self, world: &'a World) -> Option<&'a dyn Reflect>
pub fn reflect<'a>(&self, world: &'a World) -> Option<&'a dyn Reflect>
Gets the value of this Resource
type from the world as a reflected reference.
sourcepub fn reflect_mut<'a>(
&self,
world: &'a mut World
) -> Option<Mut<'a, dyn Reflect>>
pub fn reflect_mut<'a>(
&self,
world: &'a mut World
) -> Option<Mut<'a, dyn Reflect>>
Gets the value of this Resource
type from the world as a mutable reflected reference.
sourcepub unsafe fn reflect_unchecked_mut<'a>(
&self,
world: &'a World
) -> Option<Mut<'a, dyn Reflect>>
pub unsafe fn reflect_unchecked_mut<'a>(
&self,
world: &'a World
) -> Option<Mut<'a, dyn Reflect>>
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
.
sourcepub fn new(&self, fns: ReflectResourceFns) -> Self
pub fn new(&self, fns: ReflectResourceFns) -> Self
Create a custom implementation of ReflectResource
.
This is an advanced feature, useful for scripting implementations, that should not be used by most users unless you know what you are doing.
Usually you should derive Reflect
and add the #[reflect(Resource)]
component
to generate a ReflectResource
implementation automatically.
See ReflectResourceFns
for more information.
