Struct DefaultHandler 

pub struct DefaultHandler {
    pub sink: Box<dyn IoSink>,
    pub read_root: Option<PathBuf>,
    pub budget_used: RefCell<u64>,
    pub program: Option<Arc<Program>>,
    pub chat_registry: Option<Arc<ChatRegistry>>,
    /* private fields */
}

Fields

sink: Box<dyn IoSink>

read_root: Option<PathBuf>

Optional read root for io.read — when set, io.read("p") resolves to read_root.join(p). Lets tests run without touching the real fs.

budget_used: RefCell<u64>

Captured budget consumption (post-static-check, observability only).

program: Option<Arc<Program>>

Shared reference to the program, needed by net.serve so the handler can spin up fresh VMs to dispatch incoming requests. None if the handler was constructed without a program.

chat_registry: Option<Arc<ChatRegistry>>

Chat registry; populated by net.serve_ws’s per-message dispatch so chat.broadcast / chat.send work from inside a handler invocation.
