Struct Context

pub struct Context { /* private fields */ }

A libudev context. Contexts may not be sent or shared between threads. The libudev(3) manpage says:

All functions require a libudev context to operate. This context can be create via udev_new(3). It is used to track library state and link objects together. No global state is used by libudev, everything is always linked to a udev context. Furthermore, multiple different udev contexts can be used in parallel by multiple threads. However, a single context must not be accessed by multiple threads in parallel.

In Rust, that means that Context is !Send and !Sync. This means a Context must be created in the thread where it will be used. Several contexts can exist in separate threads, but they can not be sent between threads.

Other types in this library (Device, Enumerator, Monitor, etc.) share a reference to a context, which means that these types must also be !Send and !Sync.
