Crate aen_window 

Native application windows owned and composed by KnottCompositor.

One authenticated connection creates one window. Frame acknowledgements mean software adoption, not physical scanout. Applications cannot assign geometry, workspaces, focus or stacking. The compositor owns those policies.

Modules

clipboard

Bounded UTF-8 clipboard transactions on the compositor’s owner control socket. Scope zero is trusted session-operator access. Native window scopes are checked by KnottCompositor; these scopes are not a same-UID application sandbox.

Structs

Client

Nonblocking transport. Prefer WorkerWindow when application work can block.

ClientOptions

Explicit optional protocol extensions. The default keeps the original v3 handshake byte-for-byte; unsupported opt-in endpoints fail without replay.

Input

PixelBuffer

Immutable shared pixels. A server-side upload retains its aggregate memory reservation until the final compositor/upload reference has been dropped.

PointerConfinementRequest

One bounded request against the current adopted frame. Serials start at one and increase exactly once per request; a reply releases transport credit.

WorkerWindow

One window connection with one owner-held frame/request credit. Receiving an ACK on the worker does not release credit until the application drains it. No connection, frame, input or close request is replayed after an error.
