Enum AdmissionPolicy 

pub enum AdmissionPolicy {
    DropIfRunning,
    Replace,
    Queue,
}

Policy controlling how new submissions are handled when a slot is busy.

Variants

DropIfRunning

Skip task if already running.

Use when:

• You only care about the latest state
• Redundant work should be avoided
• Example: periodic health checks

Replace

Stop current task and start new one immediately.

Use when:

• New request invalidates old one
• Priority to latest submission
• Example: deployment pipeline (new commit cancels old build)

Queue

Queue the task (FIFO order).

Use when:

• All submissions must execute
• Order matters
• Example: sequential processing pipeline
