Struct ExtensionRegion 

pub struct ExtensionRegion { /* private fields */ }

RAII guard for extension lifecycle with structured concurrency guarantees.

Wraps an ExtensionManager and ensures that the JS runtime thread is shut down when the region exits. Provides:

• No orphaned tasks: the runtime thread exits on region close.
• Bounded cleanup: shutdown is capped by a configurable budget.
• Drop safety: best-effort shutdown if shutdown() was not called.

Implementations

impl ExtensionRegion

pub const fn new(manager: ExtensionManager) -> Self

Create a new extension region with the default cleanup budget (5 s).

pub const fn with_budget(manager: ExtensionManager, budget: Duration) -> Self

Create a region with a custom cleanup budget.

pub const fn manager(&self) -> &ExtensionManager

Access the inner ExtensionManager.

pub fn into_inner(self) -> ExtensionManager

Consume the region and return the inner manager (caller takes responsibility for shutdown).

pub async fn shutdown(&self) -> bool

Explicitly shut down extensions with the configured budget.

Returns true if the runtime exited cleanly within the budget. Subsequent calls are no-ops and return true.
