Enum OutputSource 

pub enum OutputSource {
    Stdout,
    Stderr,
    Combined,
}

Source of output data.

Execution only ever produces Combined. The executor merges a child’s stdout and stderr into one stream before any chunk is built, so a consumer matching on this will never see the other two from this crate — do not write a branch that depends on telling them apart, and do not read the presence of these variants as a promise that separation is available. The variants and OutputChunk::stdout exist because separating the two streams is a standing proposal, not because it happens.

They are kept rather than deleted so the day that proposal lands does not also change this type’s shape. That is a judgement, and it comes with the cost of this paragraph: a half-built structure reads as a working one unless it says otherwise.

Variants

Stdout

Standard output. Not produced by this crate — see the type’s note.

Stderr

Standard error. Not produced by this crate — see the type’s note.

Combined

Combined output. The only variant execution produces.
