attach()

void aria::binding::ViewModelScope::attach ( ViewModel & vm )

inline

Tie this scope's lifetime to the ViewModel's destructor.

Must be called from the VM's ctor body.

The hook also covers scopes owned outside the ViewModel. A scope member already cancels in its own destructor; attaching it remains harmless because cancellation and joining are idempotent.

token()

is_cancelled()

inflight_count()

cancel()

Request cancellation only (non-blocking).

cancel_and_join()

bool aria::binding::ViewModelScope::cancel_and_join ( std::chrono::milliseconds timeout = kJoinTimeoutMs )

inlinenoexcept

Cancel + synchronously wait for all in-flight coroutines to exit, with the given timeout.

Returns true on full drain.

kJoinTimeoutMs

std::chrono::milliseconds aria::binding::ViewModelScope::kJoinTimeoutMs {5000}

staticconstexpr

Default timeout for cancel_and_join() invoked from the VM's destroy-hook.

Matches the underlying CoroutineScope default and is generous enough for cooperatively-cancelled work; a stuck coroutine is reported as a leak rather than blocking process shutdown.
