Struct ItemListenerContext 

pub struct ItemListenerContext<'a> { /* private fields */ }

Read-only execution data supplied at an item, retry, or skip callback.

The context deliberately excludes job parameters, execution-context values, and durable state so a listener cannot copy them into diagnostics.

Implementations

impl<'a> ItemListenerContext<'a>

pub const fn new( correlation: &'a ExecutionCorrelation, chunk_sequence: ChunkCount, stop: &'a StopToken, ) -> Self

Constructs the borrowed callback scope.

pub const fn correlation(self) -> &'a ExecutionCorrelation

Borrows the bounded execution correlation.

pub const fn chunk_sequence(self) -> ChunkCount

Returns the zero-based chunk sequence within the step attempt.

pub const fn stop_token(self) -> &'a StopToken

Borrows the cooperative stop token.
