Struct VncClient 

pub struct VncClient { /* private fields */ }

VNC (RFB protocol) remote desktop client.

Implements a lightweight VNC client using raw TCP with tokio. The RFB protocol is simple enough (handshake → auth → framebuffer updates) that we avoid heavy C dependencies and implement it directly.

Supported encodings: Raw, CopyRect, Zlib (minimum set). Supported auth: VNC password challenge-response and no-auth.

The actual protocol implementation will be added in a follow-up.

Implementations

impl VncClient

pub async fn connect(config: &VncConfig) -> Result<Self>

Attempt to establish a VNC connection.

Currently returns an error because the RFB protocol implementation is pending. The function validates the config so callers get a meaningful message.

Trait Implementations

impl DesktopProtocol for VncClient

fn start_frame_loop<'life0, 'async_trait>( &'life0 self, _frame_tx: UnboundedSender<FrameUpdate>, _cancel: CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start the frame update loop, sending FrameUpdate messages via the provided sender until the cancellation token is triggered.

fn send_key<'life0, 'async_trait>( &'life0 self, _key_code: u32, _down: bool, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send a keyboard event to the remote host.

fn send_pointer<'life0, 'async_trait>( &'life0 self, _x: u16, _y: u16, _button_mask: u8, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send a pointer (mouse) event to the remote host.

fn request_full_frame<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Request a full framebuffer update from the remote host.

fn set_clipboard<'life0, 'async_trait>( &'life0 self, _text: String, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send clipboard text to the remote session.

fn desktop_size(&self) -> (u16, u16)

Get the remote desktop dimensions (width, height).

fn resize<'life0, 'async_trait>( &'life0 mut self, _width: u16, _height: u16, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Request the remote desktop to resize to the given dimensions. For RDP: sends a display resize request to the server. For VNC: no-op (VNC does not support server-side resize; client-side scaling is used).

fn disconnect<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Disconnect and release resources.
