Rust-XCB is a set of bindings and wrappers for XCB. It uses the XML protocol descriptions from XCB to generate the bindings and the wrappers.
Rust-XCB is only intended as an interface to XCB, so provides nothing above and beyond that.
The bindings are generated from the rs_client.py script with help from the xcbgen library (also
from XCB). The bindings are inside the ll module, which also contains the hand-written bindings
to the core library. However, all of the bindings are still in the repository, so running it is not
necessary.
The wrappers are generated from the same files, and provide a safe and more convenient wrapper over the low-level bindings by having automatic destructors for returned data, trait implementations for object "types" and other safe helpers.
The issues tracker has more details, but the high-level things that need to be done are:
