}

Internal interface of binder local or remote objects for making transactions.

This trait corresponds to the parts of the interface of the C++ IBinder class which are internal implementation details.

Required Methods

fn is_binder_alive(&self) -> bool

Is this object still alive?

fn set_requesting_sid(&mut self, enable: bool)

Indicate that the service intends to receive caller security contexts.

fn dump<F: AsRawFd>(&mut self, fp: &F, args: &[&str]) -> Result<(), StatusCode>

Dump this object to the given file handle

fn get_extension(&mut self) -> Result<Option<SpIBinder>, StatusCode>

Get a new interface that exposes additional extension functionality, if available.

fn prepare_transact(&self) -> Result<Parcel, StatusCode>

Create a Parcel that can be used with submit_transact.

fn submit_transact( &self, code: TransactionCode, data: Parcel, flags: TransactionFlags, ) -> Result<Parcel, StatusCode>

Perform a generic operation with the object.

The provided Parcel must have been created by a call to prepare_transact on the same binder.

Arguments

• code - Transaction code for the operation.
• data - Parcel with input data.
• flags - Transaction flags, e.g. marking the transaction as asynchronous (FLAG_ONEWAY).

Provided Methods

fn transact<F: FnOnce(BorrowedParcel<'_>) -> Result<(), StatusCode>>( &self, code: TransactionCode, flags: TransactionFlags, input_callback: F, ) -> Result<Parcel, StatusCode>

Perform a generic operation with the object. This is a convenience method that internally calls prepare_transact followed by `submit_transact.

Arguments

• code - Transaction code for the operation
• flags - Transaction flags, e.g. marking the transaction as asynchronous (FLAG_ONEWAY)
• input_callback A callback for building the Parcel.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
