Creating Instruction Handlers

General Setup

Now that you have most of your setup for your Voting Program, you can start defining the business logic for it.

Your program currently supports three instructions:

Create a poll
Vote on an existing poll
Close an existing poll

…and here you will implement the logic for each of them. But first, add the imports below to your processor.rs file:

Rust

use borsh::{BorshDeserialize, BorshSerialize};
use solana_program::program::invoke_signed;
use solana_program::{
    account_info::{AccountInfo, next_account_info},
    entrypoint::ProgramResult,
    msg,
    program_error::ProgramError,
    pubkey::Pubkey,
    rent::Rent,
    sysvar::Sysvar,
    sysvar::clock::Clock,
};
use solana_system_interface;

use crate::errors::PollError;
use crate::state::creator_stats::{CREATOR_STATS_SEED, CreatorStats};
use crate::state::poll::{MAX_DESC_LEN, Poll};
use crate::state::poll_option::{MAX_OPTION_NAME_LEN, PollOption};
use crate::state::vote_record::VoteRecord;
