[nodes-from-anchor] Cannot link accounts data

[Taylor123]

My IDL has an account struct called MyAccount.

The IDL has the following within an event type:

...
{
  "name": "oldState",
  "type": {
    "option": {
      "defined": "MyAccount"
    }
  }
},

In the rust client generation of this event type, MyAccount is imported as use crate::generated::types::MyAccount; rather than the correct import of use crate::generated::accounts::MyAccount;.

Rust client generation should correctly determine whether a defined struct is a type or an account and import it as such.

I'm facing similar issue in typecript client. Trying to import from types instead of accounts. Or rather, the type was not generated -

import {
  getProposalIxDecoder,
  getProposalIxEncoder,
  type ProposalIx,
  type ProposalIxArgs,
} from '../types';

Thanks for raising this. This is because in Anchor all data — including account data — is extracted as a defined type which makes it possible to link all over the place, including inside another account.

However, the nodes-from-anchor package currently puts all the account data in the account nodes making them unlinkable.

This is something we should consider for Codama v2 but in the meantime, we could duplicate the account data as a defined type so it can be linked in other places.

P.S.: These are known limitations: See #68 and #66.
