10 solana账户转换问题?

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<Outbox>, receivers: Vec<Pubkey>, amounts: Vec<u64>, data: Vec<u8>, ) -> 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(())
}

[derive(Accounts)]

pub struct Outbox<'info> { pub state: Account<'info, InitializeState>,

[account(mut)]

pub user: Signer&lt;'info>,
pub contract_token_account: Account&lt;'info, TokenAccount>,
pub contract_authority: Signer&lt;'info>,
pub token_program: Program&lt;'info, Token>,

}

[account]

pub struct InitializeState { pub owner: Pubkey, pub paused: bool, pub fee: u64, pub fee_receiver: Pubkey, pub maker_list: HashMap<Pubkey, bool>, }

[event]

pub struct OutboxEvent { pub token: Pubkey, pub to: Pubkey, pub amount: u64, pub data: Vec<u8>, }
