Enum StreamRuntimeOutcome 

#[non_exhaustive]
pub enum StreamRuntimeOutcome {
    Committed,
    Failed,
    Stopped,
    Unknown,
    ResourceBoundary,
}

The coarse, non-sensitive runtime outcome an ItemStream observes at close.

Deliberately excludes the full crate::ChunkExecutionReport: a stream’s close must react to whether the step committed, failed, stopped, or reached an unknown outcome, never to internal report machinery or other components’ data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Committed

The step attempt’s work committed durably.

Failed

The step attempt ended in a known, typed failure.

Stopped

Cooperative stop ended the step attempt.

Unknown

The step attempt’s commit outcome is unknown.

ResourceBoundary

A nested resource this stream owns reached its own logical boundary (a delegate reader exhausted, or a delegate writer rolled over) while the enclosing step attempt’s terminal outcome is not yet known.

Only ever reported by a component that nests other ItemStreams and must close a retiring delegate ahead of its own outer close – for example crate::item_components::multi_resource::MultiResourceReader/ crate::item_components::multi_resource::MultiResourceWriter closing the resource they are transitioning away from. The top-level chunk runtime itself never reports this variant: it is strictly weaker than Self::Committed (the retiring resource’s own prior work may already be durable, but the step attempt that observed its boundary has not yet reached a terminal outcome), so a delegate must not treat it as proof of a durable commit.
