Implementations

impl RawTask

pub fn new<T: Serialize + Debug>(
    task: &T,
    task_key: &str,
    task_type: i8,
    task_for: &str
) -> Result<RawTask>

pub fn from_str(
    json: &str,
    task_key: &str,
    task_type: i8,
    task_for: &str
) -> Result<RawTask>

pub fn finish_old<FI, FD>(
    &mut self,
    old: &RawTask,
    _dao_insert: FI,
    _dao_delete: FD
) -> Result<usize> where
    FI: Fn(&RawTask) -> Result<usize>,
    FD: Fn(&[u8]) -> Result<usize>, 

for performance reason, one-to-one carry which we can reuse the beginning carry to finish all flows. That way we need not to communicate with DB for create new and delete old carrier. But for failure we must redo from beginning. but I think it has small chance. Another disadvantage is the failure information will be attached to the beginning.

pub async fn save_batch<T, '_, '_, '_>(
    news: &'_ mut Vec<RawTask>,
    old_id: &'_ str,
    task: &'_ T
) -> Result<()> where
