Struct InterruptHandle 

pub struct InterruptHandle { /* private fields */ }

Thread-safe request to abort JavaScript execution on one runtime.

Obtain it from JSRuntime::interrupt_handle() or Worker::interrupt_handle(). A persistent request made with interrupt remains active until clear. For independently owned requests, prefer interrupt_scoped, which cannot be cleared by another scoped caller.

The handle remains safe to use after the runtime is gone; its local request state still changes, but there is no longer a runtime to affect.

Implementations

impl InterruptHandle

pub fn new() -> Self

pub fn interrupt(&self)

Request interruption until clear is called.

Running JavaScript is aborted on preemptive engines and new evaluations are rejected on every engine. Repeated calls are idempotent.

pub fn clear(&self)

Clear this handle’s persistent interruption request.

Scoped requests remain active until their InterruptGuard is dropped. Clearing does not resume an aborted script; it only permits subsequent JavaScript execution.

pub fn interrupt_scoped(&self) -> InterruptGuard

Request interruption for the lifetime of the returned guard.

Scoped requests compose safely: dropping one guard does not clear a persistent request or another live guard’s request.

pub fn is_interrupted(&self) -> bool

Whether any persistent or scoped interruption request is active.

pub fn mode(&self) -> InterruptMode

The interruption behavior of the bound engine.
