Provided Methods

fn init_once_get_or_create_id( &mut self, lock_op: &OpTy<'tcx, Provenance>, lock_layout: TyAndLayout<'tcx>, offset: u64 ) -> InterpResult<'tcx, InitOnceId>

fn init_once_get_or_create<F>( &mut self, existing: F ) -> InterpResult<'tcx, InitOnceId>where F: FnOnce(&mut MiriInterpCx<'mir, 'tcx>, InitOnceId) -> InterpResult<'tcx, Option<InitOnceId>>,

Provides the closure with the next InitOnceId. Creates that InitOnce if the closure returns None, otherwise returns the value from the closure.

fn init_once_status(&mut self, id: InitOnceId) -> InitOnceStatus

fn init_once_enqueue_and_block( &mut self, id: InitOnceId, thread: ThreadId, callback: Box<dyn MachineCallback<'mir, 'tcx> + 'tcx> )

Put the thread into the queue waiting for the initialization.

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>

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.
