hey @clearloop, assign me

@clearloop is there an existing error handling infrastructure?

@clearloop is there an existing error handling infrastructure?

we currently just have revert!, if I'm not mistaken, solidity errors are using revert internally as well, you can check the proc-macro implementation by @malik672 in #298, the logic is the same

the main difference are:

1. logs need to call log1, log2, log3, log4, and we need to use revert!, revert1!...revert4! (maximum 4 parameters)
2. for errors, we need to append the variables to the memory as well, then we can revert (name + parameters) together

#[derive(Error)]
pub enum Error {
  Error0,
  Error1(Bytes32),
  Error2(Bytes32, Bytes32),
  Error3(Bytes32, Bytes32, Bytes32),
  Error4(Bytes32, Bytes32, Bytes32, Bytes32)
}

// which generates

impl Error {
  fn error0() {
    zink::revert!("Error");
  }

  fn error1(param: Bytes32) {
    zink::revert!("Error", param)
  }

  // ...
}

for the revert macro, see revert!, and for the example, feel free to ask anything in the telegram channel!

great! thanks

great! thanks

see my implementation in a8a3eec, it's actually the same for this issue ^ ^
