Implementations§

impl TokenService

pub async fn recharge( pool: &Pool<Postgres>, params: TokenRechargeInsertParams, ) -> Result<RechargeResult, Error>

充值：在同一事务中插入充值记录并更新账户余额。若账户不存在则自动创建。

pub async fn consume( pool: &Pool<Postgres>, params: TokenUsageInsertParams, ) -> Result<ConsumeResult, Error>

消费：在同一事务中扣减余额并写入消费记录。余额不足时返回 Error::InsufficientBalance，不写消费记录，事务回滚。
