Enum InvariantCheck 

pub enum InvariantCheck {
    SetByThisWorker,
    Matched,
    Mismatched {
        diff: String,
    },
}

Outcome of comparing a worker’s first packet against the rung’s codec invariant. The caller — run_encoder_worker_blocking — branches on this to decide whether to keep encoding, soft-fail (requeue the chunk for another worker), or hard-fail (parse error from a malformed bitstream).

Variants

SetByThisWorker

First worker on the rung. Invariant has been recorded.

Matched

Matches the rung’s invariant. Proceed to publish.

Mismatched

Mandatory fields mismatch. Worker should requeue its chunk and exit cleanly; the rung continues with workers whose vendors agree with the invariant the first worker set. Mission- critical jobs DO NOT abort on this — only this one helper’s contribution is lost, and another worker picks up the chunk.

Fields

diff: String
