[][src]Trait deno_core::Resource

pub trait Resource: Downcast + Any + Send { }

Abstract type representing resource in Deno.

The only thing it does is implementing Downcast trait that allows to cast resource to concrete type in TableResource::get and TableResource::get_mut methods.

Methods

impl dyn Resource[src]

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

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>>[src]

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>>[src]

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>[src]

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>[src]

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn't.
