Expand description

A yield point in the coroutine.

Fields§

§state: usize

§resume_arg: Place<'tcx>

Where to move the resume argument after resumption.

§drop: Option<BasicBlock>

Which block to jump to if the coroutine is dropped in this state.

§storage_liveness: GrowableBitSet<Local>

Set of locals that have live storage while at this suspension point.
