Struct script::script_runtime::ThreadSafeJSContext
source · pub struct ThreadSafeJSContext(Arc<RwLock<Option<*mut JSContext>>>);Expand description
A version of the JSContext that can be used from other threads and is thus
Send and Sync. This should only ever expose operations that are marked as
thread-safe by the SpiderMonkey API, ie ones that only atomic fields in JSContext.

impl ThreadSafeJSContext
sourcepub fn request_interrupt_callback(&self)
pub fn request_interrupt_callback(&self)
Call JS_RequestInterruptCallback from the SpiderMonkey API.
