Trait amethyst::ecs::shred::Resource

pub trait Resource: 'static + Send + Sync + Any { }

A resource defines a set of data which can only be accessed according to Rust's typical borrowing model (one writer xor multiple readers).

Methods

impl Resource + 'static

pub fn downcast<T>(     self: Box<Resource + 'static> ) -> Result<Box<T>, Box<Resource + 'static>> where     T: Resource,

Returns the boxed value if it is of type T, or Err(Self) if it isn't.

Important traits for Box<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub unsafe fn downcast_unchecked<T>(self: Box<Resource + 'static>) -> Box<T> where     T: Resource,

Returns the boxed value, blindly assuming it to be of type T. If you are not absolutely certain of T, you must not call this.

impl Resource + 'static

pub fn is<T>(&self) -> bool where     T: Resource,

Returns true if the boxed type is the same as T

pub fn downcast_ref<T>(&self) -> Option<&T> where     T: Resource,

Returns some reference to the boxed value if it is of type T, or None if it isn't.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub unsafe fn downcast_ref_unchecked<T>(&self) -> &T where     T: Resource,

Returns a reference to the boxed value, blindly assuming it to be of type T. If you are not absolutely certain of T, you must not call this.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T> where     T: Resource,

Returns some mutable reference to the boxed value if it is of type T, or None if it isn't.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub unsafe fn downcast_mut_unchecked<T>(&mut self) -> &mut T where     T: Resource,

Returns a mutable reference to the boxed value, blindly assuming it to be of type T. If you are not absolutely certain of T, you must not call this.
