Struct WriterOutcome 

pub struct WriterOutcome {
    pub writer: Box<dyn Write>,
    pub io_error: Option<Error>,
    pub discarded: bool,
}

The reclaimed writer and deferred outcomes of a writer-backed Output, returned by Output::into_writer.

discarded is true when librnp closed the stream with a discard request — i.e. the enclosing operation failed (or the output was dropped without Output::finish) and librnp asked for the already written bytes to be deleted. The writer was not flushed in that case; a generic std::io::Write cannot delete data, so the request is surfaced here for the caller to act on (e.g. remove the partial file).

Fields

writer: Box<dyn Write>

The writer handed to Output::to_writer, closed and (unless discarded) flushed.

io_error: Option<Error>

The deferred std::io::Error from the failed write or flush, if any.

discarded: bool

Whether librnp asked for the written data to be discarded.
