Expand description
Super-trait for Binder interfaces.
This trait allows conversion of a Binder interface trait object into an IBinder object for IPC calls. All Binder remotable interface (i.e. AIDL interfaces) must implement this trait.
This is equivalent IInterface
in C++.
Provided Methods§
Implementations§
Source§impl dyn Interface
impl dyn Interface
Sourcepub fn is<__T: Interface>(&self) -> bool
pub fn is<__T: Interface>(&self) -> bool
Returns true if the trait object wraps an object of type __T
.
Sourcepub fn downcast<__T: Interface>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>
pub fn downcast<__T: Interface>(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.
Sourcepub fn downcast_rc<__T: Interface>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>
pub fn downcast_rc<__T: Interface>(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.
Sourcepub fn downcast_ref<__T: Interface>(&self) -> Option<&__T>
pub fn downcast_ref<__T: Interface>(&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.
Sourcepub fn downcast_mut<__T: Interface>(&mut self) -> Option<&mut __T>
pub fn downcast_mut<__T: Interface>(&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.
