Trait resman::Resource

pub trait Resource: DowncastSync + Debug + 'static {
    fn type_name(&self) -> TypeNameLit;
}

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

fn type_name(&self) -> TypeNameLit

Implementations

impl dyn Resource

pub fn is<__T: Resource>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

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.

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.

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.

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.

pub fn downcast_arc<__T: Resource>(
    self: Arc<Self>
) -> Result<Arc<__T>, Arc<Self>> where
    __T: Any + Send + Sync, 

Returns an Arc-ed object from an Arc-ed trait object if the underlying object is of type __T. Returns the original Arc-ed trait if it isn’t.
