在 solana 智能合约中借入时临时价值下降

Question

pub fn burn_liquidity(ctx: Context<BurnLiquidity>, _to: Pubkey) -> ProgramResult {
        let pool_account = &ctx.accounts.pool_account;
        let token1_account = &ctx.accounts.pool_token1_account;
        let token2_account = &ctx.accounts.pool_token2_account;
        let source = &ctx.accounts.source;
        let (reserve1, reserve2) = (pool_account.token1_balance, pool_account.token2_balance);
        let balance1: u64 = token1_account.amount;
        let balance2: u64 = token2_account.amount;
        let liquidity = source.amount;
        let total_supply = ctx.accounts.mint.supply;
        let amount1 = liquidity as f64 * balance1 as f64 / total_supply as f64;
        let amount2 = liquidity as f64 * balance2 as f64 / total_supply as f64;
        {
            let cpi_program = ctx.accounts.system_program.to_account_info();
            let mut cpi_accounts = UpdatePool {
                pool_account: pool_account.clone(),
            };

            let update_ctx = Context::new(
                cpi_program.key,
                &mut cpi_accounts,
                &[pool_account.to_account_info()],
            );
            let update_data = UpdateData {
                token1: pool_account.token1.to_string(),
                token2: pool_account.token2.to_string(),
                token1_amount: amount1 as u64,
                token2_amount: amount2 as u64,
            };
            update_pool(update_ctx, update_data);
        }

        
        Ok(())
    }

1.i 已经尝试了几乎所有可能的方法来消除这个错误 有人知道如何解决这个问题吗 2.And 这是 solana 区块链上的智能合约，我在其中使用了锚点 我得到的错误是：

Answer 1

            let update_ctx = Context::new(
                cpi_program.key,
                &mut cpi_accounts,
                &[pool_account.to_account_info()],
            );

update_ctx 引用临时数组，因此 Context 不能比临时数组长。预先将数组绑定到变量将解决错误。

            let acc_info = [pool_account.to_account_info()];
            let update_ctx = Context::new(
                cpi_program.key,
                &mut cpi_accounts,
                &acc_info,
            );
