pub trait Resource: DowncastSync + Debug + 'static {
// Required methods
fn type_id(&self) -> TypeId;
fn type_name(&self) -> TypeNameLit;
}
Expand description
Trait to represent any type that is Send + Sync + 'static
.
A resource is a data slot which lives in the World
can only be accessed
according to Rust’s typical borrowing model (one writer xor multiple
readers).
Required Methods§
Implementations§
source§impl dyn Resource
impl dyn Resource
sourcepub fn is<__T: Resource>(&self) -> bool
pub fn is<__T: Resource>(&self) -> bool
Returns true if the trait object wraps an object of type __T
.
sourcepub fn downcast<__T: Resource>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>
pub fn downcast<__T: Resource>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>
Returns a boxed object from a boxed trait object if the underlying object is of type
__T
. Returns the original boxed trait if it isn’t.
sourcepub fn downcast_rc<__T: Resource>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>
pub fn downcast_rc<__T: Resource>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>
Returns an Rc
-ed object from an Rc
-ed trait object if the underlying object is of
type __T
. Returns the original Rc
-ed trait if it isn’t.
sourcepub fn downcast_ref<__T: Resource>(&self) -> Option<&__T>
pub fn downcast_ref<__T: Resource>(&self) -> Option<&__T>
Returns a reference to the object within the trait object if it is of type __T
, or
None
if it isn’t.
sourcepub fn downcast_mut<__T: Resource>(&mut self) -> Option<&mut __T>
pub fn downcast_mut<__T: Resource>(&mut self) -> Option<&mut __T>
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn’t.
