Provided Methods§
fn init_once_get_or_create_id( &mut self, lock_op: &OpTy<'tcx>, lock_layout: TyAndLayout<'tcx>, offset: u64, ) -> InterpResult<'tcx, InitOnceId>
fn init_once_status(&mut self, id: InitOnceId) -> InitOnceStatus
sourcefn init_once_enqueue_and_block(
&mut self,
id: InitOnceId,
callback: impl UnblockCallback<'tcx> + 'tcx,
)
fn init_once_enqueue_and_block( &mut self, id: InitOnceId, callback: impl UnblockCallback<'tcx> + 'tcx, )
Put the thread into the queue waiting for the initialization.
sourcefn init_once_begin(&mut self, id: InitOnceId)
fn init_once_begin(&mut self, id: InitOnceId)
Begin initializing this InitOnce. Must only be called after checking that it is currently uninitialized.
fn init_once_complete(&mut self, id: InitOnceId) -> InterpResult<'tcx>
fn init_once_fail(&mut self, id: InitOnceId) -> InterpResult<'tcx>
sourcefn init_once_observe_completed(&mut self, id: InitOnceId)
fn init_once_observe_completed(&mut self, id: InitOnceId)
Synchronize with the previous completion of an InitOnce. Must only be called after checking that it is complete.
