Struct mozjs_sys::jsapi::JS::AutoSaveExceptionState
source · #[repr(C)]pub struct AutoSaveExceptionState {
pub context: *mut JSContext,
pub status: ExceptionStatus,
pub exceptionValue: RootedValue,
pub exceptionStack: RootedObject,
}
Expand description
Save and later restore the current exception state of a given JSContext. This is useful for implementing behavior in C++ that’s like try/catch or try/finally in JS.
Typical usage:
bool ok = JS::Evaluate(cx, ...);
AutoSaveExceptionState savedExc(cx);
... cleanup that might re-enter JS ...
return ok;
