+//! Functionality for communicating with Trusty services.
+//!
+//! This crate provides the [`TipcChannel`] type, which allows you to establish a
+//! connection to a Trusty service and then communicate with that service.
+//!
+//! # Usage
+//!
+//! To connect to a Trusty service you need two things:
+//!
+//! * The filesystem path to the Trusty IPC device. This is usually
+//!   `/dev/trusty-ipc-dev0`, which is exposed in the constant [`DEFAULT_DEVICE`].
+//! * The port name defined by the service, e.g. `com.android.ipc-unittest.srv.echo`.
+//!
+//! Pass these values to [`TipcChannel::connect`] to establish a connection to a
+//! service.
+//!
+//! Once connected use the [`send`][TipcChannel::send] and [`recv`][TipcChannel::recv]
+//! methods to communicate with the service. Messages are passed as byte buffers, and
+//! each Trusty service has its own protocol for what data messages are expected to
+//! contain. Consult the documentation for the service you are communicating with to
+//! determine how to format outgoing messages and interpret incoming ones.
+//!
+//! The connection is closed automatically when [`TipcChannel`] is dropped.
+//!
+//! # Examples
+//!
+//! This example is a simplified version of the echo test from `tipc-test-rs`:
+//!
+//! ```no_run
+//! use trusty::{DEFAULT_DEVICE, TipcChannel};
+//! use std::io::{Read, Write};
+//!
+//! let mut chann = TipcChannel::connect(
+//!     DEFAULT_DEVICE,
+//!     "com.android.ipc-unittest.srv.echo",
+//! ).unwrap();
+//!
+//! chann.send("Hello, world!".as_bytes()).unwrap();
+//!
+//! let mut read_buf = Vec::new();
+//! let read_len = stream.recv(&mut read_buf).unwrap();
+//!
+//! let response = std::str::from_utf8(&read_buf[..read_len]).unwrap();
+//! assert_eq!("Hello, world!", response);
+//!
+//! // The connection is closed here.
+//! ```
