Trait GlobalDynFallibleTryDropStrategy 

pub trait GlobalDynFallibleTryDropStrategy:
    ThreadSafe
    + DowncastSync
    + DynFallibleTryDropStrategy { }

A trait which signifies a try drop strategy which can fail, can be dynamically dispatched, and can be used as the global try drop strategy.

Implementations

impl dyn GlobalDynFallibleTryDropStrategy

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

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

pub fn downcast<__T: GlobalDynFallibleTryDropStrategy>( 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: GlobalDynFallibleTryDropStrategy>( 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: GlobalDynFallibleTryDropStrategy>( &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: GlobalDynFallibleTryDropStrategy>( &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: GlobalDynFallibleTryDropStrategy + Any + Send + Sync>( self: Arc<Self>, ) -> Result<Arc<__T>, Arc<Self>>

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.
