Enum TaskMode 

pub enum TaskMode {
    Periodic {
        schedule: Box<Schedule>,
    },
    OneShot {
        run_at: DateTime<Utc>,
    },
}

Execution mode for a scheduled task.

Determines how the scheduler decides when to run a task and what to do after it completes:

• TaskMode::Periodic re-computes next_run from the cron schedule after each successful execution and never removes the task from memory.
• TaskMode::OneShot fires once when now >= run_at and then removes the task from the in-memory task list and marks it done in the store.

Variants

Periodic

Run on a repeating cron schedule.

Fields

schedule: Box<Schedule>

Parsed cron schedule that drives next_run computation.

OneShot

Run once at the specified UTC timestamp.

Fields

run_at: DateTime<Utc>

The earliest UTC time at which the task should execute.
