Trait bpxe::data_object::DataObject [−][src]
Provided methods
fn try_send(
&mut self,
value: Box<dyn DataObject>
) -> Result<(), Box<dyn DataObject>>
[src]
&mut self,
value: Box<dyn DataObject>
) -> Result<(), Box<dyn DataObject>>
Try sending in a data object into this data object
If implementation is able to handle it, it should return Ok(())
, otherwise
it should return value
through Err(value)
.
This function is used primarily by DataObjectExt
implementation for Box<dyn DataObject>
. If try_send
returns Err
, DataObjectExt::send
will overwrite
the box's value with the given value.
Default implementation returns Err(value)
.
Implementations
impl dyn DataObject
[src]
pub fn is<__T: DataObject>(&self) -> bool
[src]
Returns true if the trait object wraps an object of type __T
.
pub fn downcast<__T: DataObject>(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: DataObject>(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: DataObject>(&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: DataObject>(&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.
pub fn downcast_arc<__T: DataObject>(
self: Arc<Self>
) -> Result<Arc<__T>, Arc<Self>> where
__T: Any + Send + Sync,
[src]
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.
