Required Methods§
Provided Methods§
Sourcefn compatible_with(&self, other: &(dyn OpaqueFact + 'static)) -> bool
fn compatible_with(&self, other: &(dyn OpaqueFact + 'static)) -> bool
Whether or not it is acceptable for a Patch to substitute self
by other
.
In other terms, all operators consuming self
MUST accept also accept other
without being altered.
fn clarify_dt_shape(&self) -> Option<(DatumType, &[usize])>

Source§impl dyn OpaqueFact
impl dyn OpaqueFact
Sourcepub fn is<__T>(&self) -> boolwhere
__T: OpaqueFact,
pub fn is<__T>(&self) -> boolwhere
__T: OpaqueFact,
Returns true if the trait object wraps an object of type __T
.
Sourcepub fn downcast<__T>(
self: Box<dyn OpaqueFact>,
) -> Result<Box<__T>, Box<dyn OpaqueFact>>where
__T: OpaqueFact,
pub fn downcast<__T>(
self: Box<dyn OpaqueFact>,
) -> Result<Box<__T>, Box<dyn OpaqueFact>>where
__T: OpaqueFact,
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 OpaqueFact>,
) -> Result<Rc<__T>, Rc<dyn OpaqueFact>>where
__T: OpaqueFact,
pub fn downcast_rc<__T>(
self: Rc<dyn OpaqueFact>,
) -> Result<Rc<__T>, Rc<dyn OpaqueFact>>where
__T: OpaqueFact,
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: OpaqueFact,
pub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: OpaqueFact,
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: OpaqueFact,
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: OpaqueFact,
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn’t.
