Params

This contracts contains a number of structures which are to be passed as parameters to Poll contracts. This way we can reduce the number of parameters and avoid a stack too deep error during compilation.

TreeDepths

A struct holding the depths of the merkle trees

struct TreeDepths {
  uint8 intStateTreeDepth;
  uint8 messageTreeSubDepth;
  uint8 messageTreeDepth;
  uint8 voteOptionTreeDepth;
}

ExtContracts

A struct holding the external contracts that are to be passed to a Poll contract on deployment

struct ExtContracts {
  contract IMACI maci;
  contract AccQueue messageAq;
}
