Context for the shared hostcall dispatcher.

Carries the runtime resources needed to dispatch any hostcall, regardless of whether it originated from a JS extension, WASM component, or protocol message.

Fields

runtime_name: &'a str

Runtime origin identifier (e.g. "js", "wasm", "protocol").

extension_id: Option<&'a str>

Extension that initiated the call (for policy + logging).

tools: &'a ToolRegistry

Built-in tool registry.

http: &'a HttpConnector

HTTP connector for outbound requests.

manager: Option<ExtensionManager>

Extension manager for session/ui/events dispatch.

policy: &'a ExtensionPolicy

Policy governing capability access.

js_runtime: Option<&'a PiJsRuntime>

Optional JS runtime for exec streaming.

interceptor: Option<&'a dyn HostcallInterceptor>

Test interceptor (if any).
