}Expand description
A class that performs whatever setup we need to safely make a call while
this class is on the stack. After new returns, the call is safe to make.
Fields§
§exception_global: DomRoot<D::GlobalScope>The global for reporting exceptions. This is the global object of the (possibly wrapped) callback object.
cx: JSContextThe JSContext used for the call.
old_realm: *mut RealmThe realm we were in before the call.
handling: ExceptionHandlingThe exception handling used for the call.
entry_script: Option<GenericAutoEntryScript<D>>https://heycam.github.io/webidl/#es-invoking-callback-functions steps 8 and 18.2.
incumbent_script: Option<GenericAutoIncumbentScript<D>>https://heycam.github.io/webidl/#es-invoking-callback-functions steps 9 and 18.1.
