Type Alias GraphOutput 

pub type GraphOutput = Output;

Stdout handling for a graph producer, whose captured output is a JSONL batch stream.

Aliased Type

pub enum GraphOutput {
    Ignored,
    Inherited,
    Captured,
    AsyncWrite(Box<dyn AsyncWrite + Sync + Unpin + Send>),
}

Variants

Ignored

Discards output by connecting the stream to the null device.

Inherited

Connects stdout to the parent’s stdout, with no captured output batches. Output batching settings do not apply. Consume graph execution streams to completion to observe failures; see the module example. A limited lister routes through a line-counting pipe before forwarding.

Captured

Pipes output for streaming or collection into the program’s result.

AsyncWrite(Box<dyn AsyncWrite + Sync + Unpin + Send>)

Stores an asynchronous destination and requests a pipe for the child.

Wrappers forward stdout incrementally with backpressure and flush the writer at EOF, without shutting it down. No bytes are also captured. Write/flush failures fail execution. Graph streams own the writer after successful spawning; subsequent calls on that wrapper discard stdout. Buffered wrappers retain the writer for reuse. Omitted from debug output.
