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§

Source

fn as_binder(&self) -> SpIBinder

Convert this binder object into a generic SpIBinder reference.

Source

fn dump( &self, _writer: &mut dyn Write, _args: &[&CStr], ) -> Result<(), StatusCode>

Dump transaction handler for this Binder object.

This handler is a no-op by default and should be implemented for each Binder service struct that wishes to respond to dump transactions.

Implementations§

Source§

impl dyn Interface

Source

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

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

Source

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.

Source

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.

Source

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.

Source

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.

Source

pub fn downcast_arc<__T>(self: Arc<Self>) -> Result<Arc<__T>, Arc<Self>>
where __T: Any + Send + Sync + Interface,

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.
