老师们好，我在写solana时遇到一个问题，问题代码如下，我如何将receivers(pubkey类型), to: receiver.to_account_info()是错误的，如何才能在to中使用AccountInfo类型？报错如下： he method to_account_info exists for struct Pubkey, but its trait bounds were not satisfied --> src/lib.rs:148:30 | 148 | to: receiver.to_account_info(), | ^^^^^^^^^^^^^^^ method cannot be called on Pubkey due to unsatisfied trait bounds 删掉to_account_info()则报错不是AccountInfo类型。

pub fn outbox(
    ctx: Context,
    receivers: Vec,
    amounts: Vec,
    data: Vec,
) -> Result<()> {
require!(
    ctx.accounts
    .state
    .maker_list
    .contains_key(&ctx.accounts.user.key()),
    ErrorCode::NotMaker
);
    require!(receivers.len() == amounts.len(), ErrorCode::InvalidLength);
    for (i, &receiver) in receivers.iter().enumerate() {
        let cpi_accounts = Transfer {
            from: ctx.accounts.contract_token_account.to_account_info(),
            to: receiver.to_account_info(),
            authority: ctx.accounts.contract_authority.to_account_info(),
        };
        let cpi_program = ctx.accounts.token_program.to_account_info();
        let cpi_ctx = CpiContext::new(cpi_program, cpi_accounts);
        token::transfer(cpi_ctx, amounts[i])?;
        emit!(OutboxEvent {
            token: ctx.accounts.contract_token_account.key(),
            to: receiver.key(),
            amount: amounts[i],
            data: data,
        });
    }
    Ok(())
}
