Can I use Vec<> to pass multiple accounts into an anchor program?

Question

I'm writing an escrow program for multiple assets in one swap. I was trying an effective way to input token mint & token accounts. So I tried using Vec<> as following but it poped up the following error:

Is there a solution to Vec<> error or an effective way to input multiple accounts?

Answer 1

No, you can only use the remaining_accounts functionality for adding a variable length number of accounts.

From one of the misc code examples in the anchor repo, this is how you can add a vector of remaining accounts with the ts library.

    await program.state.rpc.remainingAccounts({
      remainingAccounts: [
        { pubkey: misc2Program.programId, isWritable: false, isSigner: false },
      ],
    });

You can access them inside the program function with

ctx.remaining_accounts
