pub struct FrameExtra {
    call_id: CallId,
    protected_tags: SmallVec<[SbTag; 2]>,
}

Fields

call_id: CallId

The ID of the call this frame corresponds to.

protected_tags: SmallVec<[SbTag; 2]>

If this frame is protecting any tags, they are listed here. We use this list to do incremental updates of the global list of protected tags stored in the stacked_borrows::GlobalState upon function return, and if we attempt to pop a protected tag, to identify which call is responsible for protecting the tag. See Stack::item_popped for more explanation.

This will contain one tag per reference passed to the function, so a size of 2 is enough for the vast majority of functions.
