rust-vnc is a library implementing the VNC protocol and the client state machine. A fully functional VNC client based on SDL2 is provided as an example.
Entirely by mistake.
I've encountered a very strange failure, wherein a Xen domU with a VNC console attached to it would not send any framebuffer updates. By the time I've finally realized that my VNC clients were fine and something was wrong with Xen, it was too late: rust-vnc was practically complete. Then I spent twice as much time perfecting the handling of keyboard layouts for some reason.
To build and install the VNC client, run
cargo install vnc.
To use the VNC library in your project, add the following to
[dependencies] vnc = "^0.1"
The vnc crate implements serialization and deserialization for all of the core VNC protocol, and a largely complete client state machine.
The rvncclient executable is a quite usable VNC client, as it implements
several extensions that cut down unnecessary data transfers; as a bonus
it can be used for education and troubleshooting, as it will output
a human-readable dump of the VNC messages if ran with
I didn't really intend to write this library at all, and as such it has some drawbacks:
- No server state machine or compression.
- No encryption or authentication.
- No pixel encoding support beyond Raw and CopyRect.
- No inline documentation (but the signatures and the client could be helpful already).
That said, the library was written with the full VNC protocol in mind, and it should be straightforward to extend the library to support any of the above, should a need arise.
