Required Methods

fn clear(&mut self)

fn durable_subscribe(
    &mut self,
    flags: UpdatesFlags,
    path: Path,
    ref_by: ExprId
) -> Dval

fn unsubscribe(&mut self, path: Path, dv: Dval, ref_by: ExprId)

fn ref_var(&mut self, name: Chars, scope: Path, ref_by: ExprId)

fn unref_var(&mut self, name: Chars, scope: Path, ref_by: ExprId)

fn register_fn(&mut self, name: Chars, scope: Path)

fn set_var(
    &mut self,
    variables: &mut FxHashMap<Path, FxHashMap<Chars, Value>>,
    local: bool,
    scope: Path,
    name: Chars,
    value: Value
)

fn call_rpc(

    name: Path,
    args: Vec<(Chars, Value)>,
    ref_by: ExprId,
    id: RpcCallId
)

For a given name, this must have at most one outstanding call at a time, and must preserve the order of the calls. Calls to different names may execute concurrently.

fn set_timer(&mut self, id: TimerId, timeout: Duration, ref_by: ExprId)

arrange to have a Timer event delivered after timeout
