The kind of accuracy check that should be performed on operation when testing them.
Implementations§
Source§impl dyn Op
impl dyn Op
Sourcepub fn is<__T>(&self) -> boolwhere
__T: Op,
pub fn is<__T>(&self) -> boolwhere
__T: Op,
Returns true if the trait object wraps an object of type __T.
Sourcepub fn downcast<__T>(self: Box<dyn Op>) -> Result<Box<__T>, Box<dyn Op>>where
__T: Op,
pub fn downcast<__T>(self: Box<dyn Op>) -> Result<Box<__T>, Box<dyn Op>>where
__T: Op,
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.
Sourcepub fn downcast_rc<__T>(self: Rc<dyn Op>) -> Result<Rc<__T>, Rc<dyn Op>>where
__T: Op,
pub fn downcast_rc<__T>(self: Rc<dyn Op>) -> Result<Rc<__T>, Rc<dyn Op>>where
__T: Op,
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.
Sourcepub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: Op,
pub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: Op,
Returns a reference to the object within the trait object if it is of type __T, or
None if it isn’t.
Sourcepub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: Op,
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: Op,
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn’t.
