Enum ScenarioBoundary

pub enum ScenarioBoundary {
    BeforeOperation,
    AfterDurableCommit,

    Timeout,
    Cancellation,
    DroppedConnection,
    Cleanup,

}

Expand description

A small, target-neutral vocabulary for normal scenario fault boundaries.

Callers can still use a project-specific bounded label through FaultInjector::inject, but this type covers the lifecycle boundaries that every deterministic scenario should name consistently.

Variants§

BeforeOperation

Immediately before the business operation starts.

AfterDurableCommit

Immediately after a durable mutation commits.

BeforeResponse

Immediately before the response is projected to the caller.

DuringResponse

While a streaming response is in progress.

Timeout

At the scenario deadline boundary.

Cancellation

At cooperative cancellation.

DroppedConnection

When a client connection drops.

Cleanup

When generation-owned cleanup runs.

ResourceAcquire

When a required resource is acquired.
