Implementations

impl JsExtensionSession

pub fn load(paths: &[PathBuf], _verbose: bool) -> Result<Option<Self>, String>

pub fn load_with_context( paths: &[PathBuf], _verbose: bool, context: Value, ) -> Result<Option<Self>, String>

pub fn capabilities(&self) -> Vec<String>

pub fn tools(&self) -> impl Iterator<Item = JsToolAdapter> + '_

pub fn invoke_command(&self, command: &str, args: &str) -> Result<Value, String>

pub fn invoke_command_with_context( &self, command: &str, args: &str, context: Value, ) -> Result<Value, String>

pub fn set_runtime_context(&self, context: Value) -> Result<(), String>

pub fn set_runtime_handler(&self, handler: RuntimeHandler) -> Result<(), String>

pub fn add_runtime_handler(&self, handler: RuntimeHandler) -> Result<(), String>

pub fn shutdown(&self)

Stop the persistent Node host even when detached command/tool work still holds a clone of this session. The transport wakes those callers, and repeated calls are harmless.

pub fn custom_active(&self) -> bool

pub fn active_tools(&self) -> Option<Vec<String>>

Names of JS tools currently selected by the extension runtime. The returned list intentionally contains only the Node-side view; callers merge it with Rust built-ins before updating the harness lane.

pub fn tool_names(&self) -> Vec<String>

pub fn custom_accepts_input(&self) -> bool

Whether the active custom component should receive terminal input. Hidden overlay handles keep their promise alive but release keyboard focus back to the outer TUI.

pub fn send_custom_input(&self, data: &str) -> Result<(), String>

pub fn send_custom_input_with_consumed( &self, data: &str, ) -> Result<bool, String>

Send raw input to the Node custom component and return whether a ctx.ui.onTerminalInput listener consumed it. Hidden overlays still need to see the event for their reopen shortcut, while unconsumed input must fall through to the outer editor.

pub fn send_custom_resize( &self, width: usize, height: usize, ) -> Result<(), String>

pub fn install_ui_runtime(&self, tui: Arc<TuiAltScreen>) -> Result<(), String>

pub fn ensure_runtime(&self) -> Result<(), String>

Start the lazy Node host after all interactive runtime handlers are installed and the TUI input worker is running. Startup executes the before_agent_start lifecycle hook, which may wait on a native dialog; callers must therefore invoke this only once the dialog bridge can service pending requests.

pub fn prepare_for_prompt(&self) -> Result<(), String>

Prepare the Node runtime for one agent prompt. Starting a fresh lazy host already runs before_agent_start during its context handoff; prompts that reuse a live host send one context snapshot so the same lifecycle runs exactly once again for that prompt.

pub fn install_ui_dialog_runtime( &self, handler: RuntimeHandler, ) -> Result<(), String>

Install the host side of the small dialog protocol used by ctx.ui.select/confirm/input/editor in the Node runtime.

The handler is deliberately supplied by the interactive TUI: opening a dialog needs to swap/focus a native component and then wait for a key press, while this module only owns the Node transport. It receives both ui.dialog and ui.dialog.cancel actions and must return one of the JSON result shapes documented in node_host.mjs ({value}, {confirmed}, or {cancelled:true}).

pub fn enable_capability(&self, capability: &str) -> Result<(), String>

pub fn enable_provider_runtime( &self, provider: Arc<dyn Provider>, runtime: Handle, ) -> Result<(), String>

Install the Rust provider as the Node Pi model registry’s runtime implementation. Node receives a complete AssistantMessage; Rust remains the only owner of HTTP, authentication, retries, and provider details.
