dbus-crossroads is a library that helps you implement interfaces on object paths, i e
"server side" method handler code.
To get started, you can jump into the commented examples,
one for [sync](https://github.com/diwic/dbus-rs/blob/master/dbus-crossroads/examples/server_cr.rs)
one for [async (dbus-tokio)](https://github.com/diwic/dbus-rs/blob/master/dbus-tokio/examples/tokio02_server_cr.rs),
and one [slightly more advanced](https://github.com/diwic/dbus-rs/blob/master/dbus-tokio/examples/tokio_adv_server_cr.rs),
or familiarize yourself using [the API reference](https://docs.rs/dbus-crossroads).
It supersedes the `dbus::tree` module. Design decisions (compared to `dbus::tree`):
* First class support for both sync and async methods
* Detect method arguments automatically through generics
* ...but less generics in structs you use, which means less cluttered API
* The tree/crossroads instance is `Send` (but not `Sync`).
* You can now modify the instance from within a method handler
* It is objects (paths) that can contain custom data, and they can contain different data for different objects
* Interface descriptions are kept in a registry, which means less reference counting
