I have below enum

#[derive(Debug, RactorMessage)]
pub enum DkgEngineMessage {
    Init(usize, Vec<(usize, PeerId, MishtiPublicKey, String)>, usize),
    Round1,
    EncryptedYValuesAndCommittment((u128, HashMap<u128, Vec<u8>>, Vec<AffinePoint>)),
    Round2,
    StoreReceivedPublicKey(u128, AffinePoint),
    Round3,
}

The moment i change the value to below ,rust compiler panics


#[derive(Debug, RactorMessage)]
pub enum DkgEngineMessage {
    Init(usize, Vec<(usize, PeerId, MishtiPublicKey, String)>, usize),
    Round1,
    EncryptedYValuesAndCommitment((u128, HashMap<u128, Vec<u8>>, Vec<AffinePoint>)),
    Round2,
    StoreReceivedPublicKey(u128, AffinePoint),
    Round3,
}

More Details

I mean it seems pretty clear to me, this is a rustc panic which shouldn't happen

error: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md
