Enum StreamWriteOutcome 

pub enum StreamWriteOutcome {
    Flushed,
    Pending,
    BrokenPipe,
    Closed,
    Unknown,
}

Outcome of a single stream flush attempt.

Mirrors the paths of ClusterShell’s EngineClient._handle_write (Worker/EngineClient.py), including commit cfe0448 (“remove stream on broken pipe”).

Variants

Flushed

All buffered data was written; the stream stays registered.

Pending

The fd would block (EAGAIN): data stays buffered and the stream stays registered to retry later (upstream calls _set_writing and returns).

BrokenPipe

Broken pipe (EPIPE): the stream was removed at the point of error and must NOT be retried (cfe0448 — engines without POLLERR, like select, would otherwise never remove it and the run loop would not return).

Closed

EOF was requested and the buffer just drained: the stream was removed.

Unknown

The named stream is unknown or was already removed.
