pub enum CheckpointWatermark {
    Uninitialized,
    Idle,
    Active(i64),
}

Event-time position of a complete checkpoint cut.

Variants

Uninitialized

No active input has established a frontier.

Idle

Every channel in the cut is explicitly idle.

Active(i64)

Minimum watermark across active initialized channels.

Implementations

impl CheckpointWatermark

pub const fn cluster_min(self, other: Self) -> Self

pub const fn active_value(self) -> Option<i64>

Numeric frontier for an active cut.

pub fn validate(self) -> Result<(), String>

Reject the reserved uninitialized sentinel.

Errors

Returns an error when an active watermark uses the reserved sentinel.
