Struct x11rb_async::blocking::BlockingConnection

pub struct BlockingConnection<C> { /* private fields */ }

A Connection implementation that uses a threadpool to handle requests.

This type wraps around an existing x11rb Connection type, and makes it non-blocking by pushing all operations to a threadpool. This is good if, for instance, you have a Connection type that can’t trivially be integrated into a async runtime.

However, if you have the option of using a Connection type that is integrated into a real async reactor, you should use that instead.

Implementation

The blocking threadpool is used to handle all requests.
