error: could not compile `APP` (bin "APP" test) due to previous error

[dansiemon]

This happened with I added the DeallocateInnerPair variant to this enum:

#[derive(Debug)]
pub enum Request {
    Stats(Box<Stats>),
    Shutdown,
    FlowTableCount,
    FlowDump(Vec<FlowDetails>),
    FlowDelete(Vec<flow::Flow>),
    CheckInvariants,
    AllocateInnerPair(Option<u64>, Option<u64>), // TODO Tuples are rate in kbps, make these real types
    SetLeafParent([(u32, u32); 2]),
    DeallocateInnerPair(u32, u32),
}

There are several places in the code that exhaustively match on this enum. Once I added the new variant to all those match statements, the ICE went away.

[dansiemon]

I've updated the top-level comment. Originally it stated this problem also occurs on stable but I had made a mistake and didn't change toolchains. This has been updated to reflect this is reproducible on beta not stable.

[lukas-code]

This is #117670, which is fixed by #117686. The fix should land on beta tomorrow.

[ranger-ross]

Given that #117670 has been closed and this issue is from an old beta, I think this issue is probably good to be closed
