Struct mozjs_sys::jsapi::JS::AutoSaveExceptionState

#[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;
