+///
+/// The following example declares the local service type `BnServiceManager` and
+/// a remote proxy type `BpServiceManager` (the `n` and `p` stand for native and
+/// proxy respectively) for the `IServiceManager` Binder interface. The
+/// interfaces will be identified by the descriptor string
+/// "android.os.IServiceManager". The local service will dispatch transactions

+//! Safe Rust interface to Android `libbinder`.
+//!
+//! This crate is primarily designed as an target for a Rust AIDL compiler
+//! backend, and should generally not be used directly by users. It is built on
+//! top of the binder NDK library to be usable by APEX modules, and therefore
+//! only exposes functionality available in the NDK interface.
+//!
+//! # Example
+//!
+//! The following example illustrates how the AIDL backend will use this crate.
+//!
+//! ```
+//! use binder::{
+//!     declare_binder_interface, Binder, IBinder, Interface, Remotable, Parcel, SpIBinder,

+//! // object, BpTest, that are the typed interfaces for their respective ends
+//! // of the binder transaction. Generated by AIDL compiler.
