Instructions from a Rust client

[MartinKavik]

Hi,

Context
I've written the Rust-only example with Solana and MoonZoon (MartinKavik/voting-solana-moonzoon). And I'm just rewriting it to Anchor (MartinKavik/voting-anchor-moonzoon).

The problem
I don't use Javascript so I can't use a generated client from IDL - I create transactions and instructions in Rust code.
I was able to create "native" Solana instructions this way:

pub fn init_voting(voting_owner_pubkey: &Pubkey) -> Instruction {
    let account_metas = vec![
        AccountMeta::new(*voting_owner_pubkey, true),
        AccountMeta::new(voting_state_pubkey(voting_owner_pubkey), false),
    ];
    Instruction::new_with_borsh(crate::id(), &VotingInstruction::InitVoting, account_metas)
}

but I don't know how to rewrite the code to make it compatible with Anchor instructions.

Anchor instructions and accounts and errors are defined in /~https://github.com/MartinKavik/voting-anchor-moonzoon/blob/master/program/programs/voting_program/src/lib.rs

Thank you!

Other problems (probably suitable for new issues):

• Discord links don't work.
• How to call system_instruction::create_account_with_seed to make the account compatible with Anchor?
• How to pass a custom keypair to the command anchor deploy - an alternative to:

  solana program deploy -C ./config.yml --program-id ./keypairs/program-keypair.json ./target/deploy/voting_program.so

Have you found a solution? I'm looking for the equivalent of the following JS code in Rust.

    const program = new Program(
      idl as Idl,
      id,
      new Provider(bn.conn, null, {
        preflightCommitment: 'recent',
        commitment: 'recent',
      }),
    );

@gitmalong I was hired to write a tool to generate nice APIs for sending Anchor instructions (https://ackeeblockchain.com/blog/announcing-trdelnik-rust-testing-client-for-anchor/). Currently, it uses Rust compiler to expand Anchor program macros, then it parses the code with syn to Rust IDL and then it generates+format typed functions for sending instructions. I'm also playing with integration of Jupyter Notebook and REPL. It should be the most typed generated API because I don't need to care about JS-friendly/universal IDL and generators.
Under the hood it uses Anchor's APIs + code genereated by Anchor macros that you can always use directly as I've found out during the development (and you can see it in the link above posted by @armaniferrante )

Having the same issue as I need Rust to interact with an Anchor Program I don't have sources of. Are there any ways of interacting with them only having IDL and public key?
