Struct ChildProxy 

pub struct ChildProxy { /* private fields */ }

The water mcp front: owns the child lifecycle and forwards tool calls.

Implementations

impl ChildProxy

pub fn new( project_path: PathBuf, width: u32, height: u32, scale_factor: f64, sccache_path: Option<PathBuf>, ) -> Self

A proxy for the project at project_path; the child is not built until Self::rebuild runs.

pub async fn rebuild(&self)

Kills the current child if any, then spawns the task that rebuilds and re-drives it. Returns as soon as the build task is scheduled — callers gate on the readiness cell, not on this function.

pub async fn shutdown(&self)

Kills the child and any in-flight build. Called when the MCP session ends or the process is shutting down.

Trait Implementations

impl Debug for ChildProxy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ToolDispatch for ChildProxy

async fn restart(&self, _args: RestartArgs) -> ToolResult

restart is intercepted rather than forwarded: the child is killed, rebuilt from the current sources — picking up edits — respawned, and the fresh tree comes back through the new child’s snapshot.

fn snapshot( &self, args: SnapshotArgs, ) -> impl Future<Output = ToolResult> + Send

Read the accessibility tree.

fn find(&self, args: FindArgs) -> impl Future<Output = ToolResult> + Send

Find nodes matching a selector.

fn act(&self, args: ActArgs) -> impl Future<Output = ToolResult> + Send

Dispatch a semantic accessibility action.

fn pointer(&self, args: PointerArgs) -> impl Future<Output = ToolResult> + Send

Dispatch a pointer event.

fn key(&self, args: KeyArgs) -> impl Future<Output = ToolResult> + Send

Dispatch a key press.

fn type_text( &self, args: TypeTextArgs, ) -> impl Future<Output = ToolResult> + Send

Type text into the focused input.

fn wait(&self, args: WaitArgs) -> impl Future<Output = ToolResult> + Send

Wait for expectations.

fn screenshot( &self, args: ScreenshotArgs, ) -> impl Future<Output = ToolResult> + Send

Capture a PNG screenshot.

fn advance(&self, args: AdvanceArgs) -> impl Future<Output = ToolResult> + Send

Advance the virtual animation clock.
