Struct Controller 

pub struct Controller { /* private fields */ }

A connected emulator controller.

Status, screenshots and frames use one HTTP/2 connection and touches a second one, which halved drag-input p95 while native frames streamed (S7). The client sends no keys: without a keyboard device the emulator accepts and drops them, so Controller::keys_supported tells the driver whether keys may go this way at all.

Implementations

impl Controller

pub async fn connect( endpoint: &Endpoint, options: Options, ) -> Result<Self, Unavailable>

Opens both connections and reads the hardware through getStatus. Any failure, including a port that accepts connections and never answers, makes the endpoint Unavailable.

pub fn serial(&self) -> &str

pub fn hardware(&self) -> Hardware

The display size and keyboard flag read at connection time.

pub fn keys_supported(&self) -> bool

Whether keys and text may be sent through the controller: only when the AVD declares a keyboard (hw.keyboard=yes).

pub async fn touch(&self, points: &[TouchPoint]) -> Result<Duration, Error>

Sends one touch event holding points on the main display and returns the round trip. The emulator acknowledges once it has scheduled the event, not when the app received it.

pub async fn tap(&self, x: i32, y: i32) -> Result<(), Error>

Presses and lifts contact 0 at (x, y), in display pixels.

pub async fn screenshot(&self) -> Result<Frame, Error>

A raw RGB888 capture at the display’s full resolution.

pub async fn frames(&self, working_width: u32) -> Result<FrameStream, Error>

Subscribes to RGB888 frames scaled by the emulator to working_width pixels (0 for the display size). The emulator sends a frame whenever the guest posts one, changed or not, and nothing while the screen is still.
