+//! 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,
+//! StatusCode, TransactionCode,
+//! };
+//!
+//! // Generated by AIDL compiler
+//! pub trait ITest: Interface {
+//! fn test(&self) -> binder::Result<String>;
+//! }
+//!
+//! // Creates a new local (native) service object, BnTest, and a remote proxy
+//! // object, BpTest, that are the typed interfaces for their respective ends
+//! // of the binder transaction. Generated by AIDL compiler.
+//! declare_binder_interface! {
+//! ITest["android.os.ITest"] {
+//! native: BnTest(on_transact),

+//! SpIBinder::FIRST_CALL_TRANSACTION => {
+//! reply.write(&service.test()?)?;
+//! Ok(())
+//! }
